Using S+ 2000, R3 on Win98. I have a minor puzzle dealing with how to incorporate the loop increment into a vector name for a vector created inside of a loop. As a toy example, suppose I have a simp
Thanks to all who have responded to my query on naming a vector in a loop (including at last check Andy Liaw, James Holtman, Leonid Bigiansky, brgrxha, John Brogger and counting). Clearly I have been
Another solution to my query was provided by Mark Fisher, and is included b<-5 for (j in 1:5){ vector<-paste("tmp.",j,"<-numeric(b)",sep="") eval(parse(text=vector)) } In addition to the previous lis
Hello all, Using S-Plus 2000, R3 on Win 98. I have a data set (actually several) which by the way they were constructed have reps 1 & 2 in sequential, repetitive order for each treatment . The code b

Hello all, I have a data extraction problem when using unpaste to crop out the field information desired from the rate and rateUnit columns. Below is a portion of the data frame in question. d.df[c(1
I received one response from Don MacQueen to my question regarding the use of unpaste to extract information from a column with a variable number of delimited fields. The solution arrived at is to pa
Using S-Plus 2000 on W98 machine I have generated a series of box plots (bwplot) with the following script, where CROP is a factor with 6 levels, V is a numeric injury measurement and trtmnt is a fac
I apologize for what may be a simple question, but a search of FAQ's, V&R and the manuals have not given me a solution. I am attempting to simulate termite behavior with regard to selection of feedin
I would like to thank Coen Bernaards, Alan Zaslavsky, Tony Plate, Robert Balshaw, Lutz Prechelt, Todd Taylor and Christian Keller for their suggestions on coding a numeric vector using breaks or grou
