Dear all, I would like to know if there is an easy to transform a vector of strings to a vector of integers. Ex: ("ab","ab","bb","cat","cat","ab") will be (1, 1, 2, 3, 3, 1) Thx, Naira -- View this message in context: http://www.nabble.com/From-strings-to-numbers-tp17315179p17315179.html Sent from the R help mailing list archive at

Dear R experts, Wish you all a HAPPY NEW YEAR! How do I go about plotting (using lattice) overlays of an ID (group=ID) observed, fitted data in each panel of a multiple panel plot (each panel identified by DS1 + DS2 + DS3)? "x" variable is X1 in the accompanying section of a dataset. each individual is identified by color and Y's are identified by "pch" or "lty".

Documentation on how to put classes and methods in packages with namespace? How should I define my classes and methods in "dynamicGraph"??? (That is - Can some one point me to the documentation on how to put classes and methods in packages with a namespace? ) Currently it is done by the code below. This gives problems, when a workspace with a "dynmaicGraph" is

Hi, I have a vector of strings (categories), each element of which can be uniquely found in each element of a much longer vector of about 30 or so differeint factors. I would like to define another factor variable (drawn from NewFactorListaccording to which string from "categories" is found in the longer string of factors. Then I'd do it again, with another set of categories, and make a table based on the new factors. The last part is easy, but I've never had luck with string manipulation in R. for(j in 1:lengt...

Re. the Kings Quest game called R, Inspired by the "stats4" of R-1.9.0 (alpha of 2004-03-15) I moved the body af my function ".onLoad.dynamicGraph" to the end of ".../dynamicGraph/R/dynamicGraph" (replacing "library(methods)" by "require(methods)"). The secound run, with [Previously saved workspace restored], produces the same result as in
