I want to read a .csv file with R, but my data frame contains scientific numbers like 13E07.

How do I convert these into numeric in R?

library("data.table") 
df <- fread(header=TRUE, sep = ";" , "path/file1.csv"  , select = c("Column2", "Column3", "Column4"))

The default is to use "." as a decimal separator. Set `dec=","` in your `fread()` call and it should read them as numeric. – MrFlick May 31 '22 at 14:59
perfect MrFlick, that resolved my problem (dec=",") – vlad May 31 '22 at 15:05
