It is a promising solution. Yet, there is room for improvement. I
revise the if condition so it won't throw an error during ordinary
startup.
.First <- function() {
if (length(commandArgs(T))>0 && commandArgs(T)[1] == "ld"){
load(commandArgs(T)[-1], .GlobalEnv)
}
}
For the Rload script, it should be:
gnome-terminal --command "R --args ld '$1'"
Note the single quotation of $1. Without it, it does not work if the
file name contains space.
