Barplot: Vertical bars with long labels
Dear List, I need a barplot with vertical bars. Each bar should have a label. The problem is, that the labels are too long, so they overlap, or only every seccond label is displayed in the output. Here is a little syntax: dd <- c(100,110,90,105,95) barplot(dd,names.arg=c('Conduct Disorders','Attention Deficit', 'Eating Disorders',

Excessive use of LLVM_FALLTHROUGH?
I came across a weird-looking use of LLVM_FALLTHROUGH which I think is completely spurious, but I figured I should check with the group mind before ripping it out. Basically, if you have multiple cases with no code in between, you do *not* need LLVM_FALLTHROUGH, right? switch (Foo) { case Bar1: LLVM_FALLTHROUGH; // not needed case Bar2: some code; return; case Bar3:

fixrbconfig - does it work on intel macs?
I''m trying now to do "sudo fixrbconfig" in the terminal, and I get this: /usr/lib/ruby/1.8/powerpc-darwin8.0/ruby.h does not exist.

[PATCH 4/6] vhost_vdpa: support doorbell mapping via mmap
Given the need for 4K doorbell such that QEMU can easily map, ect, and assuming that I have a HW device which exposes 2 VQ's, with a notification area off of BAR3, offset=whatever, notifier_multiplier=4, we don't need to have 2 x 4K pages mapped into the VM for both doorbells do we? The guest driver would ring DB0 at BAR4+offset, and DB1 at BAR4+offset+(4*1). The 4K per DB is useful how?

Sometimes commands do not terminate after upgrading to R 4.0 and Ubuntu 20.04
I have upgraded R (from 3.6 to 4.0) and RStudio (from 1.1 to 1.2.5) a few days ago, and Ubuntu from 18.04 to 20.04 yesterday. Since then, R sometimes never terminates when executing certain commands: ivreg (from package AER), summary (of a logit regression) and logitmfx (from package mfx). Sometimes these commands run fine, but most of the time I have to kill the process because R won't

Problem adjusting x-labels with bargraphCI
Hello: I'm having quite a bit of difficulty adjusting the x-labels using bargraphCI. I've tried using text and srt=45 to rotate the labels or mtext for 2 lines to break up the labels. However, using either method, I cannot line up the labels with the midpoints of the bars (they line up with some sort of tick mark that is off the midpoint of the bars). Any suggestions would be greatly

Dear List, I'm exploring the use of class inheritance for a package were developing. I want to try to build on existing a class, i first want to extend this a bit using a virtual class and then extend this virtual class in multiple other classes.
