Hi all,
I have the following data
AAA 1e+06 1222.312
AAC 100.2 0.33
However the following command
dat <- read.table("mydat.txt");
print(dat)
n1 <- sum(as.matrix(dat$V1));
gives:
Error in sum(as.matrix(dat$V1)) : invalid 'type' (character) of argument
What's wrong with the data type so that it gives such error?
