Inverse Gaussian Distribution
...(agecat,ordered=TRUE), contr.treatment(n=6,base=3))) The variable 'area' goes from A to F (6 areas: A,B,C,D,E,F) How can i manipulate the data to set the baseline of area to C? R is producing errors when I'm trying to do so. I'll be very thankful for any help you can provide.

Frequency table to histogram
I have read a frequency table in to R called "temp." I now want to create a histogram table from it, but I obviously first have to expand the data - to the sample size of 100. I want to use the command rep(), but I'm not sure how to go about it..I tried using the code: temp1<-rep(temp$Chest,100) hist(temp1) But this creates a v. odd histogram so I know it must be wrong!

rsync on Interix WSU 3.5
