I am wondering if it is possible to perform the following two basic functions with primitive R functions. I know I could write functions for either, but it seems as though they are probably built-in somewhere. 1) Fill out a vector to a desired length with missing values or zeros. So, x<-c(3,4,5) f(x,5) 3,4,5,NA,NA
For the NA case, see ?length.
2) Find the [row,col] location of a particular value in a matrix, eg x<-matrix(1:9,ncol=3) f(x,2) 2,1 Thanks.
