how to use the switch statement
Good morning,
I am trying to recode the values of a column in a data frame and,
instead of using a long series of if/else statements I would like to use
a switch (as it is, for instance, in the C programming language).
I have a column of this type:
AT
BB
B1
B1
CC
CC
T6
B1
CC
BB
TT
AT
AT
AT
TT
BB
...
and I need to change this coding (if it's AT then it should be A1, if
it's BB then

overlapping labels
Good evening,
I am trying to add labels to the point of a simple plot, using the
text() function; the problem is that sometimes, if two points are too
close to each other, labels overlap and are no longer readable.
I was wondering whether there are options that I can use to prevent this
overlapping (by, for example, placing labels alternatively above and
below the plotted curve), or whether I

Merge: how can I keep discarded values?
Good morning,
I am merging two datasets and I would like to save the non-matching rows
in a separate file.
The problem is how to retrieve the non-matching rows in R.
Example:

A4 Sandro
A5 Luca
DATASET B
code book
A1 Guerra e Pace

plot.new?
Hi all,
I am just beginning to use R and encountered a problem in trying to draw a
regression line using the command "abline(coef(var)" and similar ones but
got the error "plot.new has not been called yet". Does anybody know how can
I call plot.new? Is this an additional package to be found somewhere on the
web? Is it a functionality that I just have to "activate"

Adopting a third-party JSON library
Hi,
I'm a new contributor. I'm considering the possibility of adopting a third-party JSON library instead of LLVM's homegrown `lib/Support/JSON.cpp`. The way I see it, this would bring several advantages as well as some downsides:
+ Slimmer codebase.
+ Benefit from upstream work and active contributions to another project.
+ Possibly improved performance and API ergonomics.

Package: logcheck-database
Severity: wishlist
Hi!
if autossh debug is enabled it logs to syslog, thus the messages go thru

so this is the ignore line
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ autossh\[[0-9]+\]: .*$
