[R] differential use of R version

Dear all, please could you advise me on the following : on a server, in a folder "x86_64-redhat-linux-gnu-library", i have 2 versions of R (below), with the corresponding BioC libraries : > 3.2 > 3.3 how could i preferentially use an R version or the other (with the related BioC libraries) ?

[R] taking a small piece of large tiff

Dear Forum  I am trying to cut out a small section of a very large 2-dimensional grayscale image as a tiff in R, but it is having difficulty handling such large files.  I have looked at bigmemory and ff packages but it is unclear how I can use these packages with tiffs. Can anyone please

Re: [R] system call removes special characters from text output

Hello everyone, Again, I apologize for not providing a reproducible example. There was a small (but important) bug in my R code having nothing to do with system(), this is now fixed, and everything is working as expected this morning. The lesson for me is time to stop coding after 10 PM. Thank

Re: [R] system call removes special characters from text output

The "whatever information" would be the usual minimal reproducible example. Since you think your code works at the shell level, make up an example with a system call to "echo". Then state what you expect to happen and what happens instead. B. > On Apr 4, 2017, at 12:44 AM, stephen sefick

Re: [R] R function stopped working

Daniel, if you wish to learn from your mistakes them you must listen. Peter is not someone whose input you should dismiss. The function you have showed us never worked as you have described it. However, if you give .GlobalEnv as the first argument in the call to ls() then it should work. You

Re: [R] R function stopped working

Thanks! I was not aware of the browser() function, seems pretty useful for debugging. However, for this particular case, adding it to the mentioned function doesn't do much: Again I get no errors, no output in the terminal and no files are created. If I include browser() within the for-loop

Re: [R] Converting date vector into a serial date number

I think it is important to point out that treating dates or times as serial numbers should only be done for importing or exporting data. Rather, once the conversion to one of the ?DateTimeClasses has occurred you are better off leaving it as such to reduce the brittleness of your code. For one

Re: [R] R function stopped working

Maybe a daft question arising from lack of reproducible example, but have you run ls() manually to make sure there are objects that _exactly_ match "_Figs_" ? The simplest explanation for a loop doing nothing is that there are no cases. S Ellison > The following function is supposed to search

I discourage the use of print() for debugging. Put a browser() statement into your loop and when execution takes you to the debugger interface, examine your variables and expressions one by one. B. > On Apr 4, 2017, at 10:09 AM, DANIEL PRECIADO wrote: > > To your

Re: [R] R function stopped working

To your first comment: Yes, the function used to work, and the loop inside it still does (as indicated in my first email). I wouldn't bother asking otherwise. To your second, no, specifying the environment in the ls() call doesn't help, the problem persist. On Tue, 2017-04-04 at 15:26 +0200,

[R] Converting date vector into a serial date number

I have a data frame. One column (call this column a) contains years, like 1871, and another column (call this column b) contains months, like 2. I need to convert these year-month combinations, stored in these two date vectors, into a single serial date number. E.g. year 1871 and month 2, stored

Re: [R] R function stopped working

Thanks, but printing doesn't work within the function either. (i.e, no result or output, or error). Also, like I said, the loop is working fine on its own (so the path, name, filename, and all other variables called from the function exist, are available and are recognized just fine). It just

How about inserting print() statements on the output of "ls()" and the value of "filename". In particular, is the value of Plots_path the same as last week? -pd > On 4 Apr 2017, at 10:50 , DANIEL PRECIADO wrote: > > The following function is supposed to search the

The following function is supposed to search the workspace and save plots  (i.e. listing all objects in the workspace named "Figs", which are all ggplot2 plots, and saving them as png files) SaveFigs <- function() { for (i in ls(pattern="_Figs_")) { filename =

Re: [R] matafor package - categorical moderator interpretation question

You are not conducting a proper test of the moderator. When you use 'mods = ~factor(sample_data$Participants) - 1', the model does not include an intercept term but dummy variables corresponding to all levels of the moderator. The omnibus test you are getting therefore tests the null hypothesis
