[R] Beginners question

[Koen Hufkens]

Dear list,

I've been messing around with coding functions in R and it just won't make 
sense to me.
Running my analysis by hand on command line is fine and works but because 
of the repetitive nature of the job I would like to code a function for it.

My problem:

I would like to read in data from a file in my current working dir.

so my code would look like:

myanalysis <- function(sample, samplenr){
sample.samplenr <- read.geodata("sample.samplenr", arg, arg etc.)
sample.samplenr.results <- someanalysis(sample.samplenr)
}

problem is that charater values aren't interpretated as they should. Any 
tips and tricks? This should be fairly simple but I just can't find any 
reference to it. Most input values in functions in R are numeric or are 
strings to be interpretated with bolean statements but aren't handled as 
input variable perse.

Suggestions and comments would be greatly appreciated,
Koen.
