Good moorning,

yesterday, i asked for how we can import data into R i found that it is necessary to make the file in csv format then use L<- read.csv2("path of file")
now i see that the dimension of my table importing into R is 1 colonne (i have realy 20) and (655555) the number of all my lines in the excel file (i want to have only the 2600 lines in my table)
Also, when i say to do this L[c(1,2,5)] it is not work coluns not define!!!!

someone have an idea?

thanks
