...o export one that uses plot() then lines(). however, it seems that the jpeg format and the pdf format only takes the first line plot, and doesn't even consider the additional plots. My code is the following: output_file<-paste(filez,".pdf",sep="") pdf(output_file) plot((x_data) ~ (y_data), main = filez) lines (x,z,col="red") dev.off() The pdf only comes out with the graph of the plot, and not of the lines.

If x is a data.frame containing a column of mode character, this column is changed to a factor after applying fix(x). Example: R> x_data.frame(a=1:3,b=letters[1:3],c=c("hansi","pepi","karli")) R> x$c_as.character(x$c) R> is.character(x$c) [1] TRUE R> is.factor(x$c) [1] FALSE R> fix(x) ## I change "karli" to "sepp" R> x$c [1] hansi pepi sepp Levels: hansi pepi sepp...
