HELP me please with import of csv to R

Hi,

Hey,

I am having problems with importing a csv file to R.

I could read the file by typing:
read.csv(file="/Users/kama/Desktop/skatter.csv", header=TRUE, sep=";")

So that command does work?

However, i can not analyze the "skatter" - for ex, when i type:     skatter
= read.csv("skatter.csv")

Then you need the above command, not what you type here:

skatter <- read.csv(file="/Users/kama/Desktop/skatter.csv",
header=TRUE, sep=";")

But note that if sep=";" then you don't have a csv file and should
properly use read.table() instead.

i get this message:

Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :

What i need is to import this file and analyze it using for example
histogram.

I have Mac(update) and the file is saved in csv file... and I'm quite new
user of R.

That error means that R can't find the file where you told it to look.
Specifying the full and complete path as in your first example should
work.

If you're having problems with paths (which are a Mac issue and not at
all an R issue), you could also try

read.table(file.choose(), header=TRUE, sep=";")

I think that file.choose() should work on Mac.

The Intro to R document that came with R might also be of use.
