In mrparker909/doWhile: Implements a doWhile loop.

doWhile

Package implementing a do while loop in R.

Install

library(devtools)
devtools::install_github("mrparker909/doWhile")

Examples

If you don't mind assigning global variables such as k:

k <<- 0
doWhile({k<<-k+1; print(k)}, {k<5})
rm(k)

If you don't want global variables:

doWhile(do={k=k+1; print(k)}, While={k<5}, vars=list(k=0))

or alternatively:

doWhile({if(!exists("k")) {k<-1} else {k<-k+1}; print(k)}, {k<5})

If you want a return variable:

K = doWhile({k <- k+1; print(k)}, {k<5}, {k}, list(k=0))
print(K)

And the same as above, but more explicit:

K = doWhile(do     = {k <- k+1; print(k)}, 
            While  = {k<5},
            Return = {k},
            vars   = list(k=0))
print(K)
