spec_tbl_df is over 10 times slower on same opperations as a normal tibble

Asked 2021-Jun-15 at 14:37

So I was really ripping my hair out why two different sessions of R with the same data were producing wildly different times to complete the same task. After a lot of restarting R, cleaning out all my variables, and really running a clean R, I found the issue: the new data structure provided by vroom and readr is, for some reason, super sluggish on my script. Of course the easiest thing to solve this is to convert your data into a tibble as soon as you load it in. Or is there some other explanation, like poor coding praxis in my functions that can explain the sluggish behavior? Or, is this a bug with recent updates of these packages? If so and if someone is more experienced with reporting bugs to tidyverse, then here is a repex showing the behavior cause I feel that this is out of my ballpark.

This is the issue I had in mind. These problems have been known to happen with vroom, rather than with the spec_tbl_df class, which does not really do much.

vroom does all sorts of things to try and speed reading up; AFAIK mostly by lazy reading. That's how you get all those different components when comparing the two datasets.

With vroom:

How do I make geom_bar colors change with gganimate when x and y are constant?

Asked 2021-Jun-15 at 01:12

I'm new to gganimate and was having difficulty figuring out how to do this.

I'd like to show the spread in two different levels of a variable by animating colour transitions. I want to show this by having the narrow level transition through a smaller range of colours than the wider level in the same amount of time. Is this possible?

Here's the reproducible example I have up-to now.

You used lookarounds that are non-consuming patterns, while you need to use consuming pattern to let the regex engine reach minutes after hours.

The function week_no is not vectorised so you would need some kind of loop to iterate over each value after strsplit. In the for loop you use sapply, so we can use the same here.

What does read_csv() use random numbers for?

Asked 2021-Jun-10 at 19:21

I just noticed that read_csv() somehow uses random numbers which is unexpected (at least to me). The corresponding base R function read.csv() does not do that. So, what does read_csv() use the random numbers for? I looked into the documentation but could not find a clear answer to that. Are the random numbers related to the guess_max argument?

"Collapsing" data columns

Asked 2021-Jun-10 at 03:01

can I please get some help wrangling this messy dataset?

The following reprex describes treatments + start/stop dates for five patients. The columns Line1, Line2, Line3 describe the order the treatments were administered (i.e. first treatment, second treatment, etc). However, you can see that the data has been entered such that certain patients don’t have their first treatment in the fist column. For example, ID3's first tx was TreatmentD, but it has been entered into Line3. To complicate matters, some columns have been skipped altogether between consecutive treatments (e.g. ID4).

Vulnerabilities

No vulnerabilities reported

Install reprex

or get a development version from GitHub:. On Linux, you probably want to install xclip or xsel, so reprex can access the X11 clipboard. This is 'nice to have', but not mandatory. The usual sudo apt-get install or sudo yum install installation methods should work for both xclip and xsel.
