c = concatenate / combine
Try help(c) or under the 'Vector and Assignments' section of An
Introduction to R.

You have to put the folder 'faraway' into c:/.../R/rw1061/library/
where ... is your path to R and rw1061 could be rw1062 ect depending on
your version.

Subject: [R] faraway tutorial: cryptic command to newbie

I am just about working through Faraways excellent tutorial "practical
regression and ANOVA using R"

on page 24 he makes the x matrix:
x <- cbind(1,gala[,-c(1,2)])

how can I understand this gala[,-c(1,2)])... I couldn't find an
explanation of such "c-like" abbreviations anywhere.

thanks for a hint.

another problem: I couldn't load the faraway library, using the
library() command, even though I specified the path, .. do I need to put
library files into a certain directory? I always got an error: Error in
library(faraway) : There is no package called `faraway'

Thanks a lot

christoph
