Hi, I uninstalled my R's 1071, and installed R1081. But now, it appears that I cannot read in files using the same commands that I used previously. The command I type is m<-read.csv("E:/T6.25.8.02.StdDates.csv", header=TRUE, sep=",",quote="\"",dec=".",fill=TRUE) The error gives me is Error in file(file, "r") : unable to open connection Look forward to your insight.
