Re: [R] assigning values to elements of matrixes

Hi Matteo From assign help page x a variable name, given as a character string. No coercion is done, and the first element of a character vector of length greater than one will be used, with a warning Nothing is said about matrices and dimensions here so I wouldn't expect that assign can

Re: [R] assigning values to elements of matrixes

Dear Matteo, Here's a function that does what you want and that you should be able to adapt to your problem. It does have the disadvantage of copying the object twice (beyond the overhead of assigning to the indexed value): myassign <- function(x, index, value, envir=.GlobalEnv, ...){ object

Correct me if I'm wrong, but I think the mode of operation is that you run a local Rstudio, which connects to Rstudio server via protocol which lets the two Rstudios communicate via Internet ports. I don't think you can just run Rstudio via a Putty connection. As others have pointed out,

This sounds like more of an operating system task than an R task. But within R, you can come close, I would think, by copying all of the packages' directories to the same directory as the script. Then write another script that will install all of the packages. In the future, run that script
