Hello,
The defaults in read.csv2 are ";" as the separator and "," as the
decimal symbol. It seems that the file you import is not a true csv
since it mixes up two norms.
You can solve your problem in defining the dec option equals to ".":
read.csv2("test.csv",dec=".")->don

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.
With my best regards,
Pascale Voirin
