Dear R folks,
I have several data sets I want to process automatically using R. I
found littler [1] and thought this will do the trick.
1. Read in data file to a data frame using `scan()`.
2. Do linear regression.
3. Write the data and the coefficients back to a file.
#!/usr/bin/env r
if (is.null(argv) | length(argv)!=1) {
cat("Usage: auswertung.r datafile \n")
q()
}
filename <- as.character(argv[1])
d = data.frame(x=scan("/tmp/data"))
write(sum(d$x), "/tmp/data.result", ncolumns=1)
Could someone help me how I can substitude `/tmp/data` with the value
stored in `filename`? I do not get it to work using `do.Call` or
`paste()`.
Thanks,
Paul
