today <- Sys.Date()
nextmo<- paste0( month.abb[ as.numeric(format(today, format="%m"))+1] ,
format(today,"%Y") )
[1] "Jun2016"

pdf() opens a graphics device, so you need a function that establishes a
coordinate system:
x5 <- runif(15, 5.0, 7.5)
pdf(file=" test.pdf");
plot(1,1,type="n")
text(1, 1, paste(round(x5, 2), collapse="\n") )
dev.off()
I doubt that this is what you really want, and suspect you really need to be
studying the capabilities supported by the knitr package. If I'm wrong about
that and you want a system that supports drawing and text on a blank page, then
first study:

If you choose that route then the text "R Graphics" by Paul Murrell will be
indispensable.
