Bug in

Rapidminerpartner

Hello, everyone

I found a bug in "Execute R" operator

I am using R-3.6.0

Briefly, "Execute R" cannot compute mean function of R

I did

data[1,1] <- mean(data[3:5,4])

but it didn't work and why it didn't is written in the log file I attached

I believe it will not be able to compute var function either.

I attached the process and log files.

Please fix this problem for me

Thank you and have a nice day.

Best,

yyhuang

Hi@Rapidminerpartner

It seems that R'smeandoes not behave well with dataframes. One workaround is to convert the data to a regular matrix before taking the mean:

data[1,1] <- mean(data.matrix(data[3:5,4]))
