Hi, I would appreciate if someone can give me a pointer on how to save a webpage programmatically using R. For example, let say I have this webpage open in my browser: http://www.bseindia.com/stock-share-price/dabur-india-ltd/dabur/500096/ When manually I save this page, I just press Command+S (using Mac) and then this page get saved in hard-disk Now I want R to mimic this same job that I do

Hi, when I need to download some package I use for example install.packages("fBasics") function. However simply using that function needs additional intervention to select the server from which I want to download. I would like to ask the list how I can put additional argument in the install.packahes() function to stop showing that pop-up? While looking into the help page I guess

Below is my full implementation (tried to make it simple as for demonstration) Lapply_me = function(X = X, FUN = FUN, Apply_MC = FALSE, ...) { if (Apply_MC) { return(mclapply(X, FUN, ...)) } else { if (any(names(list(...)) == 'mc.cores')) { myList = list(...)[!names(list(...)) %in% 'mc.cores'] } return(lapply(X, FUN, myList)) } } Lapply_me(as.list(1:4), function(xx) { if (xx ==

Hi, Following expression returns only the first element ifelse(T, c(1,2,3), c(5,6)) However I am looking for some one-liner expression like above which will return the entire vector. Is there any way to achieve this?

The 'webshot' package (on CRAN) can do this.

The reason that it works for Apply_MC=TRUE is that in that case you call mclapply(X,FUN,...) and the mclapply() function strips off the mc.cores argument from the "..." list before calling FUN, so FUN is being called with zero arguments, exactly as it is declared. A quick workaround is to change the line Lapply_me(as.list(1:4), function(xx) { to Lapply_me(as.list(1:4),

My modified function looks below : Lapply_me = function(X = X, FUN = FUN, Apply_MC = FALSE, ...) { if (Apply_MC) { return(mclapply(X, FUN, ...)) } else { if (any(names(list(...)) == 'mc.cores')) { myList = list(...)[!names(list(...)) %in% 'mc.cores'] } return(lapply(X, FUN, myList)) } } Here, I am not passing ... anymore rather passing myList On Sun, Mar 4, 2018 at 10:37 PM,

O/S: Linux R version : 2.2.1 The R server doesn't have http internet access. And the sys admins will not install the R libraries that I requested. So I have downloaded the packages that I want to intall and have moved them into my home directory on the server. These are a series of *.tar.gz files. I want to install the R libraries in my home directory, but I can't get it to work.

Hi, When using the "Packages --> Install packages from local zip files" menu item in the windows-gui: 1) is that supposed to automatically pull in dependencies (in that case I have to fix something in my package). 2) If that's not the default: is there a way to make it so? Thanks, Joh

That's fine. The issue is how you called Lapply_me(). What did you pass as the argument to FUN? And if you did not pass anything that how is FUN declared? You have not shown that in your email.

Hi Joshua, thanks for your prompt reply. However as I said, sum() function I used here just for demonstrating the problem, I have other custom function to implement, not necessarily sum() I am looking for a generic solution for above problem.
