Hello,
        I have two problems in automating multiple glm(s) operations.
The data file is tab delimited file with headers and two columns. like

"ABC"  "EFG"
1  2
2  3
3  4
dat <- read.table("FILENAME", header=TRUE, sep="\t", na.strings="NA",
dec=".", strip.white=TRUE)
dataf <- read.table("FILENAME", header=FALSE, sep="\t", na.strings="NA",
dec=".", strip.white=TRUE)
norm1 <- glm(dataf[1,1] ~ dataf[1,2], family= normal(log), data=dat)
norm2 <- glm(dataf[1,1] ~ dataf[1,2], family= normal(identity), data=dat)
and so on.

But glm does not work on the data unless I write ABC and EFG there... I want
to automate the script for multiple files.

The other problem is to write the plot(GLM) to a file without  displaying it
at stdout.

Thanks,
