As the title says, I normally use ctrl + shift + c to comment out multiple lines of code in Rstudio. It no longer works (nothing happens when I use the above shortcut).
I am using Rstudio version:

I have had look in "Global options" but cannot see any setting relating to multiline commenting and in the "keyboard shortcuts help" section it still lists ctrl + shift + c as the correct shortcut. Anyone know what my issue could be?

I am not sure wether this is the right place for this question, but I've upgraded my R from 3.6.3 to 4.2.2 and my experience has been that the 4.2.2 version is way slower than the older one in some cases. Is this really an issue with R 4.x compared to R 3.6.x or do I need to adjust anything on my setup?
I found this link regarding a problem similar to mine with R 4.0.2: https://github.com/rocker-org/rocker/issues/412
Sample code (runs on average twice as fast on 3.6.3 than on 4.2.2)
I know this could be a package implementation issue rather than an R version issue, but I had problems with other scripts that do not use any of the packages below
library(tictoc)
library(seasonal)
times <- c()
for(j in 1:100) {
print(j)
tic()
for(i in 1:20) {
try({ final(seas(ts(1:120 + runif(120), start = c(1990, 1), frequency = 12))) })
}
elapsed <- toc()
times <- c(elapsed, unname(elapsed$toc - elapsed$tic))
}

To add any non-ASCII characters in R documentation using roxygen2, the encoding must be declared using the tag #encoding.
So when °C is used in the roxygen code, adding the tag #encoding UTF-8 will render it correctly for html as well as pdf.
This can be checked with
path <- "path to Rd file"
tools::checkRd(path)
I am having issues receiving proper utf8 characters using rmongodb.

Using mongo shell I am getting:
"organization" : [
{
"name" : "Birkhäuser Verlag GmbH",
}
],
In RStudio:
[1] "WERK Birkhäuser Verlag GmbH"
To get the data in R, I am using:
mongo.find.all(mongo = mdb, ns = colname, limit = 10)
So the Umlaut is not handled properly.
Any help much appreciated!
I am reading input text file line by line with the following function:
lines_reader<-function(filename){
conn<-file(filename,open="r")
linn<-readLines(conn,encoding="UCS-2LE")
close(conn)
return(linn)
}
If I try to plot these lines in the R enviroment, letters with accent marks are treated not adequately appearing like "Ã" or "è" instead of "à" or "è".
How to cope with this? What encoding I should choose?

How about changing the encoding that you are using:
lines_reader<-function(filename){
conn<-file(filename,open="r")
linn<-readLines(conn,encoding="UTF-8")
close(conn)
return(linn)
}
