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
I ran into a missing graph issue while developing histograms and geometry bar plots in r using the ggplot function. The issue is intermittent and occurs across multiple data sets. One data set, the largest, is described here.
My initial code, used to generate randomized data, is this:
...ANSWER
Answered 2021-Mar-23 at 18:43The issue is that you are using scale_y_binned()
. The rest of the code works fine for me, except when I add this particular line to the plot. The "binning" is working (your y axis has %'s), but you see no geoms because ultimately, ggplot2
is plotting the histogram using the same geom used for geom_bar
/geom_col
. This geom requires a continuous y axis, and scale_y_binned()
is designed to "bin" or "discretize" the y axis. So... the bars are being plotting on both charts, but once binned, ggplot2
has no idea how to draw your geom.
As for why you're seeing the inconsistency... not sure. Sometimes there is a time component to executing the code. When I run your code, it consistently gives me the second chart (no bars).
To fix, you need to use scale_y_continuous()
and set the labels.
QUESTION
Description
This issue appears to apply to vectorised and loop approaches to renaming several files. Vectorised approach used in reprex below. The bug only seems to present when filenames do not contain meaningful or alphanumeric strings.
Summary
Existing files prior to file.rename:
"1.R" "2.R" "3.R" "4.R" "5.R".
Existing files following file.rename:
"6.R".
Expected output:
"2.R" "3.R" "4.R" "5.R" "6.R"
Reprex
...ANSWER
Answered 2021-Mar-20 at 09:03Is 6.R actually the content of 1.R?
I think you are seeing 1.R renamed to 2.R and over-writing 2.R in the process. The new 2.R to 3.R etc.

QUESTION
I get a mobile number from the user. I will check and capture existing records in a HTML. I want to display this to the user and then I want to ask the user to enter choice whether to add a new record or not.
The below code is working. Only problem is the HTML window is closing on its own. The user is not able to view it.
I want the HTML must be closed manually before the next step.
Any help will be appreciated.
I am open to any other method.
...ANSWER
Answered 2021-Feb-25 at 08:32I believe your goal as follows.
- You want to keep the dialog of
SpreadsheetApp.getUi().showModalDialog(userInterface, cusmob )
, until the user close the dialog.
- When
SpreadsheetApp.getUi().showModalDialog(userInterface, cusmob )
is run, the process of this dialog is released from the process of the running function. By this, the next script of the function is run. SoSpreadsheetApp.getUi().prompt()
overwrites the existing dialog. By this,SpreadsheetApp.getUi().showModalDialog(userInterface, cusmob )
is removed soon. I think that this is the reason of your issue.
In order to achieve your goal, I would like to propose the following 2 patterns.
Pattern 1:In this pattern, the sidebar is used instead of the dialog. In this case, please modify your script as follows.

I would like to install devtools to my version of R version 3.5.1.
Problem
When I install the package devtools, I get the following error:
...ANSWER
Answered 2021-Feb-13 at 22:40Your simplest fix is to either:
- Install a newer version of R (!!recommended!!)
- Use a snapshot mirror such as the ones from provided by microsoft at https://mran.microsoft.com/snapshots/{date} (replacing {date}) as the
mirror
argument ininstall.packages
. By looking at https://cran.r-project.org/bin/windows/base/old/ we can see thatR-3.5.1
was replaced byR-3.5.2
in december 2018. So I would suggest using2018-11-31
as your snapshot mirror.

QUESTION
I have been stuck with this for more than an hour. So the test bench is at the bottom, and the answer is supposed to show 120 but I keep getting 20. I believe it only does 5 * 4 not the rest of 3 2 and 1. What is the problem??
I tried to fix all the other ones but they seem correct. is it a calculation error? is it WHILE problem?
...ANSWER
Answered 2020-Nov-20 at 17:38When evaluating WHILE
you need to make sure the inner expression is evaluated as a WHILE
. But you are evaluating it just as itself. In other words, the recursive call to eval
should be passing e
but you are just passing e2
.
As a result you're just getting two evaluations of the loop, which gives 20.
So it seems to me.
QUESTION
I found out that reprex::reprex
can't read the ¦
character (and some other special character like "é") and throws an error. Is there a way to have reprex work with the local encoding (here French locale) ?
Reprex

Answered 2020-Nov-08 at 18:28It is hard to reproduce your environment even with withr
package.
In my environment it always works correctly.
This solution from tidyverse

QUESTION
Is there a way to calculate the difference between each group efficiently? Ideally, I want to create a new column with mutate()
function to show the difference (in one column, in a long format). I don't want to have to do compute the difference between each group individually.
i.e. I want to find the difference in values between each group, on a given date and hour:
arc1045 - arc1046,
arc1045 - arc1047,
arc1045 - arc1048,
arc1045 - arc1050,
arc1046 - arc1047,
arc1046 - arc1048,
.
.
.
The data frame can be retrieved using the code below.
...ANSWER
Answered 2020-Nov-03 at 14:30You can put your data frame into long form with pivot_longer
, then do a full_join
to get all combinations by date
, hour
, and row number. Using distinct
you can get unique combinations and remove duplicates (e.g., arc1045
- arc1046
and arc1046
- arc1045
).
