Hi,
I want to create variable names from within my code, but can't find any documentation for this.
An example is probably the best way to illustrate. I am reading data in from a file, doing a bunch of stuff, and want to generate variables with my output. (I could make a "list of lists" and name all the elements, but I really want separate variables.)
#################
#This is just a dummy example, please excuse any shortcuts...
data <- read.table("file", ....)
animals <- (data[,animal])
animals
> "cat", "dog", "horse" # Not known what these are before I read the data file
# do a bunch of stuff
mean_cat <- abc
var_cat <- dfd
mean_dog <- 123
var_dog <- 453
etc..
##############
I thought of trying to use the paste() function to create the variable name, but that doesn't work:
for( animal in animals){
paste("mean", animal "_") <- 123
}
Any ideas???
Thanks
