Hello,

No data is attached. Maybe try

dput(head(failuredf, 30))

?

And where can we find non-base PivotTable? Please start the scripts with 
calls to library() when using non-base functionality.

Hope this helps,

Rui Barradas

To follow up on Rui Barradas's post, I do not think PivotTable is an R
command.

You may be thinking og the "pivot_longer" and "pivot_wider"
functions in
the {tidyr} package which is part of {tidyverse}.
