QUESTION
The example below is a simple one which tries to assert the column y is always positive (y>0). How can I extract the errored data (row 3 with the negative value,into a dataframe maybe, or any convenient object) while allowing the workflow to continue with "cleaned" data?
...ANSWER
Answered 2021-Apr-12 at 09:23This is tricky, and the answer below doesn't solve this 100%. Now there are a number of different ways assertr lets you handle errors/stops, just see ?error_stop (which is the default).
You need to not only filter out rows that fail, but also collect them (all) for later inspection.
Below I wrote my own error handler. It fetches those rows that fail, filter them away, and stores them in the global environment under the varibale my.failed.rows
.

QUESTION
When I try to use the new-ish ragg::agg_png()
device with ggplot2::ggsave()
, the image does not appear to save correctly.
Take the following reprex. I make a simple plot and then save it using the agg_png()
function directly, and with ggsave()
. The image saved with the agg_png()
device directly comes out as expected. However, when I use ggsave()
, it's almost like the units are being ignored. You can't tell, but there is a tiny image beneath the final code output. In that output, we can see that the image is only 7x7 px, even though inches have been specified by the units. From this blog post, it doesn't seem like anything extra should be required to make ggsave()
work beyond setting device = agg_png
.
Are there additional parameters I need to specify? Including session info in case there is something system-specific going on.
...ANSWER

device is in px

QUESTION
I am stuck on this small problem. This is how my Excel data looks like:
I have a UserForm which asks for the "Hue", "Munsell Value" and "Munsell Chroma" values, and it should give the value in column D (the color name) as output in a Message Box. I am trying to loop until the last non-empty row and check A, B, C columns for matching data and then give out the corresponding 4th column as output.
This is my VBA code:

QUESTION
This may be a usage misunderstanding, but I expect the following toy example to work. I want to have a lagged predictor in my recipe, but once I include it in the recipe, and try to predict on the same data using a workflow with the recipe, it doesn't recognize the column foo
and cannot compute its lag.
Now, I can get this to work if I:
- Pull the fit out of the workflow that has been fit.
- Independently prep and bake the data I want to fit.
Which I code after the failed workflow fit, and it succeeds. According to the documentation, I should be able to put a workflow fit in the predict slot: https://www.tidymodels.org/start/recipes/#predict-workflow
I am probably fundamentally misunderstanding how workflow is supposed to operate. I have what I consider a workaround, but I do not understand why the failed statement isn't working in the way the workaround is. I expected the failed workflow construct to work under the covers like the workaround I have.
In short, if work_df
is a dataframe, the_rec
is a recipe based off work_df
, rf_mod
is a model, and you create the workflow rf_workflow
, then should I expect the predict()
function to work identically in the two predict()
calls below?
ANSWER
Answered 2020-Oct-19 at 19:49The reason you are experiencing an error is that you have created a predictor variable from the outcome. When it comes time to predict on new data, the outcome is not available; we are predicting the outcome for new data, not assuming that it is there already.
This is a fairly strong assumption of the tidymodels framework, for either modeling or preprocessing, to protect against information leakage. You can read about this a bit more here.
It's possible you already know about these resources, but if you are working with time series models, I'd suggest checking out these resources:
QUESTION
Upon opening a project on rstudio i have the following Warning:
...ANSWER
Answered 2020-Sep-15 at 22:47I think this is ultimately a small bug in renv
. Here's my guess at what's happening:
While this project has been initialized as an
renv
project, it does not have a lockfile for some reason. (Perhapsrenv::activate()
was called to initializerenv
without explicitly creating a lockfile?)The project has an
renv
autoloader; this is from a script atrenv/activate.R
. That script is configured to loadrenv 0.11.0
.When the project is loaded,
renv
finds thatrenv 0.12.0
is installed in the project library, not the expected version0.11.0
. This causes the warning to be emitted. (Perhapsrenv
was updated in that project previously?)
So, ultimately, the warning is misleading here -- the request for renv 0.11.0
comes directly from the autoloader, not from the lockfile (which does not exist). As for why the lockfile does not exist, I'm not sure -- but it most likely implies the project was initialized via renv::activate()
, and not by renv::init()
.
All that said -- you can safely re-generate the lockfile via renv::snapshot()
.

I'm new to HTML and interactive tables, and I'm having trouble building a table container to add headers for my data set. Is there an easy way to insert table headers for my data set? I want columns 2-5 (excluding date in column 1) and columns 6-9 to have header 'Sector' and 'Industry' respectively.
I've included an extract of the dataset below.
Thank you!

QUESTION
I've put together a data preprocessing recipe for the recent coffee dataset featured on TidyTuesday. My intention is to generate a workflow, and then from there tune a hyperparameter. I'm specifically interesting in manually declaring predictors and outcomes through the various update_role()
functions, rather than using a formula, since I have some great plans for this style of variable selection (it's a really great idea!).
The example below produces a recipe that works just fine with prep
and bake(coffee_test)
. It even works if I deselect the outcome column, eg. coffee_recipe %>% bake(select(coffee_test, -cupper_points))
. However, when I run the workflow through tune_grid
I get the errors as shown. It looks like tune_grid
can't find the variables that don't have the "predictor" role, even though bake
does just fine.
Now, if I instead do things the normal way with a formula and step_rm
the variables I don't care about, then things mostly work --- I get a few warnings for rows with missing country_of_origin
values, which I find strange since I should be imputing those. It's entirely possible I've misunderstood the purpose of roles and how to use them.
ANSWER
Answered 2020-Jul-22 at 00:14The error here occurs because on step_string2factor()
during tuning, the recipe starts trying to handle variables that don't have any roles, like species
and owner
.
Try setting the role for all of your nominal variables before picking out the outcomes and predictors.
QUESTION
This is a direct follow up to How to interpret ggplot2::stat_density2d.
bins
has been re-added as an argument see this thread and the corresponding github issue, but it remains a mistery to me how to interpret those bins.
This answer (answer 1) suggests a way to calculate contour lines based on probabilities, and this answer argues that the current use of kde2d
in stat_density_2d would not mean that the bins can be interpreted as percentiles.
So the question.
When trying both approaches in order to get estimate quintile probabilities of the data, I get four lines as expected using the approach from answer 1, but only three lines with bins = 5
in stat_density_2d
. (which, as I believe, would give 4 bins!)
The fifth bin could be this tiny little dot in the centre which appears (maybe the centroid??)???
Is one of the ways utterly wrong? Or both? Or just two ways of estimating probabilities with their very own imprecision?
...ANSWER
Answered 2020-May-15 at 15:47I'm not sure this fully answers your question, but there has been a change in behaviour between ggplot v3.2.1 and v3.3.0 due to the way the contour bins are calculated. In the earlier version, the bins are calculated in StatContour$compute_group
, whereas in the later version, StatContour$compute_group
delegates this task to the unexported function contour_breaks
. In contour_breaks
, the bin widths are calculated by the density range divided by bins - 1
, whereas in the earlier version they are calculated by the range divided by bins
.
We can revert this behaviour by temporarily changing the contour_breaks
function:
