...called from a shell script. This code has worked fine all these days on hundreds of files, but with the particular set I'm working with now, when I run the above command, I get the error message: > for (i in list.files(pattern = "*.dmp")) { currentfile <- read.table(i) vecrawrts <- as.vector(currentfile$V3) residuals <- residuals(lm(v ....
