Dear R users, I have a problem with plot option in R. I want to plot all columns values in a single graph and the labels of x axis the row names. I try to use matplot option, but I have a problem with labels and thickness. I use a very complex data with 10 columns and 406 rows. I use this code: > matplot(data.matrix(data1), type="l",xaxt="n") > axis(1,

Hello all! I have a problem with R. I want to extract regression coefficients from summary and use it for compute the theoretical values.
