Hello everybody out there using R,
How can I import data with a numeric header from a .csv-file?
My file example.csv has the following content (a duplicate measurement of
potentials for three different currents):
1; 2; 6
1.0; 2.1; 5.9
1.1; 2.0; 6.0
I try to import the data by using:
measurement <- read.table("example.csv",sep=";",header=T)
However, the values in the header are renamed to the column names X1, X2 and X3.
When I try to plot the data, I don't get the right x-values (the three
different currents 1, 2 and 6), but 1.0, 2.0 and 3.0:
plot(mean(measurement))
I got X1, X2 and X6, because 1, 2, and 6 aren't legal variable names.
If you want to use them as names anyway, use the check.names=FALSE argument.
I don't know how you tried to plot them so I can't help you with that.
