Dear tinytex users
I install knitr and tinytex with the following line commands in RStudio
and it seems to work:
install.packages("knitr")
install.packages('tinytex')
In the long past I was told to also run the following lines but now they
do not seem to be needed.
#update.packages(ask = FA
p.s. But now I click some (but not all) .R file and cannot see the
source code.

I have a data frame containing variables "yr3",...,"yr28".
How do I remove them with a wild cardsomething similar to "del yr*"
in Windows/doc? Thank you.

R will still print 3 decimal places for the third column since it
wants them to be of the same format, but each number is 2 sigfigs.

Hi, I have two variables with 86 observations each. Below I print with
the print command with digit=2. But, I am getting three decimal places

t() doesn't print, it returns a value. In R, there's auto-printing in
the toplevel
I have a "list" containing four elements, as shown below:

Printing this in a main program causes no problem (as shown above).
But, using the command t(mycontrol) the line gets ignored. Any idea? Thanks.

I have had an issue with printing (with cat) in a subroutine for which I
do not have a applicable example, but I am still hoping to get some
help. In the following, the first block of code works fine.
...
t<-abs(me)/se; p<-2*(1-pt(t,nrow(x)))
sig<-my.sig.levels(p)
out<-data.frame(round(cbind(m
to start looking for a problem. Hand
calculation can use pencil and paper or Excel or other tools. It is a tedious
task but very effective.

Dear All
I updated to R-4.0.0. and also installed the latest Rtools 4.0 (to now
the new default folder c:\rtools40). While compiling a package (binary)
I received the follow marning message saying Rtools is required. Any
clues? Thanks.
