overwrites your XYZ dataframe. If you want to keep XYZ, you will want to
name the newly created frame differently.

Betreff: [R] How do I delete a row from a data frame when varA == "TRUE"
I want to delete a row from a data frame XYZ where A == "TRUE". Let's
assume there are five variables in this data frame XYZ. My deletion is
based on the TRUE vs. FALSE value under variable A. How do I do this?
Thanks!
My current code:
for (i in 1:length(XYZ$A)) if (XYZ$A == "FALSE") XYZ<-XYZ else XYZ<-
XYZ[-i,]
Error message is:
Error in if (XYZ$A == "FALSE") XYZ<-XYZ else XYZ<- XYZ[-i, :
missing value where TRUE/FALSE needed
Please help!!
