[R] misclassification matrix

HI Everyone, I am working with the following situation. I have n observations and j possible outcomes and each one of the n observations is assigned a class from 1 to j. Furthermore, this process is done m times (for some large m 1000). What I want to do is create a misclassification matrix

Re: [R] Inheritance and automatic function call on script exit

If you are running these interactively, you could make your own source() function.  In that function you could define the super and subscripts, and have it call writeOutput on.exit().  I suspect you could get something like that to work even in batch mode by having R load the function by

Jake, The interaction2wt function in the HH package does something similar. Please look at its examples and see if it satisfies your current need. Look especially at the examples with simple=TRUE. install.packages(HH) ## if you don't already have it library(HH) example(interaction2wt) On Wed,

[R] replaces a matrix of NAs in an array with the previous matrix with numbers

Dear list, Does anyone know if there is a function that replaces a matrix of NAs in an array with the previous matrix with numbers? For example, I have an array ab - array(dim=c(3,3,15),dimnames=list(rows=1:3,cols=1:3,dim=times)) . Select out put from the array is: , , dim = 0.478356969557745

Re: [R] Inheritance and automatic function call on script exit

1) It would be better if you understood R scripts as functions. R, possibly using either the proto or oo package, has at least 4 inheritance schemas that I know of. None will do what you want, asaik. 2. ?on.exit will tell you what you did wrong below. 3. If I understand your query correctly, I

Re: [R] Source awareness?

Over the years I've seen lots of requests concerning how to conveniently call scripts from other scripts. The S (R S+) language is oriented towards functions, not scripts (or macros), and many of the requests are for things easy to do in functions (or packages of functions) but not in scripts.

Apparently, the same issue exists in SAS, where there is an option to run the Ward algorithm based only on the distance matrix. Perhaps, a SAS user could confirm that or even check with SAS. Peter -- View this message in context:
