Indexing and partially replacing 99, 999 in data frames
Dear WizaRds, unfortunately, I have been unable to replace the '99' and '999' entries in library(UsingR) attach(babies) as definitions for missing values NA, because sometimes the 99 entry is indeed a correct value. Usually, or so I thought, NAs can easily replace a, say, 999 entry via mymat[mymat==999] <- "yodl" in a matrix or data frame. Alas, the babies'

Conditional Selection of Columns for Tables

return() in nested functions
Dear WizaRds, After consulting different sources I am still unable to understand the correct use of return() in nested functions. To illustrate the problem: f <- function(x,y,type){ est1<-function(x,y){ z=x+y out(x,y,z)} est2<-function(x,y){ z=x*y out(x,y,z)} out<-function(x,y,z) return(x,y,z) if (type=="est1") est1(x,y) if (type=="est2") est2(x,y) }

Package Building under Windows with MikTeX 2.6
Dear WizaRds, I wrote a small function in R and would like to create a package. The necessary documentation is done, Rtools etc. are installed and I am still unable to complete the process under Windows. I did extensive research in the archives and read the Murdoch-Sutherland website on the Rtools and MikTeX hints. I realize that I understand only half or less of what is said there
