Hello, I have a problem with the variable type defined by reading a csv file with read.csv2.
Here is a test file saved as < test.csv > : var1;var2;var3 TI;1995;4.5 VD;1990;4.8 FR;1994;3.9 VS;1993;5.1 FR;1995;4.7 FR;1992;5.8 That I read in R with : read.csv2("test.csv")->don;don don$var3 ## [1] 4.5 4.8 3.9 5.1 4.7 5.8 ## Levels: 3.9 4.5 4.7 4.8 5.1 5.8 as.double(don$var3) ## [1] 2 4 1 5 3 6 Why is it by default a <levels> type ? And how can I get the decimal value for var3 Thanks a lot for your answer.
