当我使用 tidyverse 中的“传播”功能时，RStudio 继续崩溃

Question

I'm trying to spread a dataframe, but R continues to crash everytime I try. I can use other functions from the tidyverse, like mutate, filter, etc, but I'm unable to use spread. When I try to cancel the code, a Terminate R dialog box pops up explaining that R is not responding to my request to interrupt the current operation and that I should terminate R.

I've tried uninstalling and then reinstalling tidyr and tidyverse, but no luck.

Does anyone have an idea as to why this might be happening or a possible solution to the problem?

Answer 1

I had this problem once. I noticed it occurs after use group_by and summarize. dplyr converts the new dataset class to "grouped_df" "tbl_df" "tbl" "data.frame" and for some reason that I don't know spread does not work properly.

If that is your case, just force the class to be data.frame with the as.data.frame (dataset) command before submitting your dataset to the spread function.

It worked for me!
