Hi R users,
I have a problem on how to pass an extra argument to do. call:
The example codes are:
#--------------------------------------------
require(ggplot2)
plots = lapply(1:5, function(.x) qplot(1:10,rnorm(10), main=paste("plot",.x)))
require(gridExtra)
do.call(grid.arrange, plots)
#---------------------------------------------
I want to force the composite figures into 2 rows by adding 'now = 2'
in the function 'grid.arrange'. How can I do it?
I searched on google but could not find a workable solution.
I am working on RStudio 0.98.1102 on OSX Yosemite 10.10.2.
Thanks a lot,
Bingzhang
