Hi everybody,

I tried to pass a filepath to a function in R, but I failed =/ I hope someone here can help me.

>heat <- function(filepath) 
{ chicks <- read.table(file=filepath, dec=",", header=TRUE, sep="\t")
...
}

When I call the function, nothing happens...

>heat("/home/.../file.txt")

... and "chicks" is not found

>chicks
Error: Object 'chicks' not found

What is the correct way to pass a path to a function?

Best wishes from Germany, Phil
