similar to: Import selected columns from sas7bdat file

hi, the sas universal viewer might be a free, non-R way to convert a sas7bdat file to non-proprietary formats, not sure if it's windows-only. those other formats should be easier to import only a subset of columns into R.. https://support.sas.com/downloads/browse.htm?fil=&cat=74 On Thu, Aug 10, 2017 at 7:42 AM, peter dalgaard <pdalgd at gmail.com> wrote: > I had a look at this

I had a look at this a while back and it didn't seem to be easy. The path of least resistance would seem to be to use SAS itself to create a data set with fewer columns, but of course that requires you to get access to SAS. Otherwise, I think you'd have to modify sas7bdat::read.sas7bdat to drop unselected columns. That function is pure R code, so it might not be quite as hard as it

I had a look at the current code, and AFAICT it has essentially the same structure as it did back then. I think it may have finally dawned upon me what the issue really is: The logic is that in Rf_addX11Device, we have if (!X11DeviceDriver(dev, display, width, height, ps, gamma, colormodel, maxcubesize, bgcolor, canvascolor,

OK, this is now in R-devel, but only superficially tested (b/c this is a Mac).

OK, so I did the archaeology anyway.... This was the story, R-core November 29, 2001. Part of thread "X11 still segfaults". ------------>> ..... Gah. I've been too tired today. Why did that take me so long? The culprit seems to be R_ProcessEvents((void*) NULL) in newX11DeviceDriver This gets called *before* this stuff at the end of Rf_addX11Device dd =

Spoke too soon, both systems now build, but neither has the original bugs fixed....

Just a quick heads-up, mostly for those who want to keep their packages up to date with respect to updates of R: We intend to have a patch release on October 31. Nickname and detailed schedule will be made available on developer.r-project.org in due course.

I tested it. It fixes the bug and didn't seem to produce any errors. Thank you Professor Dalgaard! I'm so glad this has finally been addressed. I will update the bug report.

Is someone on-list authorized and willing to make the documentation change? I suppose I could learn what it takes to be a "player", but for such a trivial fix, it probably is overkill. Dissenting opinions?

John, The Windows installation instructions document has the following. So, one obvious question is whether you did select it. (I haven't installed on WIndows for ages, so I don't know whether this was changed recently or even whether the selection is on or off by default). -pd Using package tcltk =================== The package tcltk supports building graphical interfaces with Tcl/Tk.

My (also not expert) understanding is that there is nothing insecure about alternative certificate chains at all. All browsers and macOS's built in SSL library (secure transport) support them properly. OpenSSL and LibreSSL were/are simply broken. This was not such a big issue so far, but now that some old long lived certificates are expiring, it is increasingly an issue. FWIW it is possible
