I am newcomer to R and I am loborating on this problem:
How do I import data from a CD into R for further evaluation.
Using code "newgotcha <- read.table("e:\\asciiwin\\gotcha.dat") "
returmns a list containing an additional column with indices. The
command "plot (gotcha)" gives the expected plot. However, the line
hist(gotcha) returns the message "Error in hist.default(newgotcha) : `x'
must be numeric".
Um, you read `newgotcha' so what did you expect "plot (gotcha)" to do?
How can I get the data in an accessible from into R.
Please read `An Introduction to R' and note the difference between read.table() and read.table(header=TRUE). If that is not sufficient, please read the R Data Import/Export manual.
Any suggestions are appreciated. Andreas Andreas Betz andreasbetz at earthlink.net [[alternative HTML version deleted]]
