Dear All, I want to compare formulas resulting from using stepAIC() on glm() objects. I have 2 different formulas, say F1 and F2, which consist of about 10 factors (Y~A+B+C+...) but one has an interaction term (A:B) while the other doesn't. But when I perform F1==F2 it comes back as TRUE. Is there a proper way to compare formulas? ------------------------------------------- Jeffrey M

Hello, I have a workspace that contains a number of functions I want to put in a library. Under R 1.9.0 I did this fairly easily by putting them in a R folder, creating a DESCRIPTION & TITLE file etc. I could then load my library successfully.

All, I have used package.skeleton, edited the .Rd files and the DESCRIPTON file. In one of my package functions I am using RODBC so I have a line of code that reads: require(RODBC). In my DESCRIPTION file I have the following relevant line: Depends: R (>= 2.9.0), RODBC However, when I do a check (Rcmd check my_package_name) I get this warning: * checking for unstated dependencies in R code

However, when I include the function in a package and run "R CMD check pkgname" it gives this error message: '\+' is an unrecognized escape in character

Hello, I want to plot 3 boxplots [ par(mfrow=c(3,1)) ] but the first one has 8 groups, the 2nd has 7 and the third has 6. But I the groups to line up: 1 2 3 4 5 6 7 8 2 3 4 5 6 7 8 3 4 5 6 7 8 where the numbers actually refer to years. I suspect I have to manipulate the function bxp().

Then I run the following R-code: library(foreign) sashome <- "/Program Files/SAS/SAS 9.1" test<-read.ssd(file.path(sashome), "pcb", sascmd = file.path(sashome,

Ah OK, and what about generating the libguestfs-live-service for centos ?
