I ran a function in R three days ago and the execution time was about 4
minutes. I ran the same function yesterday and the execution time was more than
6:50 minutes(I aborted the function after that time).
I read in the Internet that this is possible. I also came to know that software

Hi All,
I am new to R and am wondering if there is a way to pass arguments
between rscripts. I have this working but have had to create a C# shell
calling the scripts in sequence via windows scripting which enables command
line arguments to get the necessary interaction.
I'm wonder

thank you for your reply
well, you are resorting to a supposed order of i which is not necessary the
case, and in fact is not in mine...
consider this example, please
d<-data.frame(i=c(8,12,3), s=c('97,918,19','103,1205', '418'), stringsAsFactors
= FALSE)

Nothing magic to suggest.
But maybe:
list.s <- strsplit(d$s,",")
r <- data.frame(i=rep(d$i, times=sapply(list.s, length)), s=unlist(list.s),
stringsAsFactors=FALSE )

You mean like this?

(Obviously, this could be a one-liner)

The environment variable R_MAX_VSIZE is read at start-up so need to be
set outside R. If you are starting R from a shell you can use
env R_MAX_VSIZE=700Gb R
If you use a GUI you might need to set the variable in another
way.
Here is a reproducible version of your example:
hertz <- 6000
# considering this data.frame as a reproducible example
d<-data.frame(i=c(1,2,3), s=c('97,98,99','103,105', '118'), stringsAsFactors =
FALSE)
d
#I need to get this final result
r<-data.frame(i=c(1,1,1,2,2,3), s=c(97, 98, 99, 103, 105, 118))
r

Thanks so much for taking a look at this.
Before setting a new value, I opened a fresh session of R and checked to see
whether there was any value set for R_MAX_VSIZE. There was not, so we'll assume
the default as you described.
Next, I tried to set a value with
Sys.setenv("R_MAX_VSIZE" = 8e9
Good morning. Over the weekend I worked through this tutorial on bloggers.com

This item in NEWS explains the change:

the maximal vector heap size. On macOS, unless specified by this
environment variable, the maximal vector heap size is set to the
