Did you use read.table(filename, ..., dec=",") when importing the data (so "30,3" is read as the number 30 and 3 tenths instead of as the character string "30,3")?
Whenever importing data follow up by using str() or summary() on its output, before doing any further analysis. E.g., > bad <- read.table(header=TRUE, text="x y\n1,1 2,1\n1 2\n") > str(bad) 'data.frame': 2 obs. of 2 variables: $ x: Factor w/ 2 levels "1","1,1": 2 1 $ y: Factor w/ 2 levels "2","2,1": 2 1 > good <- read.table(header=TRUE, dec=",", text="x y\n1,1 2,1\n1 2\n") > str(good) 'data.frame': 2 obs. of 2 variables: $ x: num 1.1 1 $ y: num 2.1 2 Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On > Behalf Of F86 > Sent: Wednesday, July 11, 2012 2:40 AM > To: r-help@r-project.org > Subject: Re: [R] HELP me please with import of csv to R > > Thank you!
