changing names with different character sets
Dear R People:
I'm trying to replicate something that I saw on an R blog.
The first step is to load in the .rda file, which is fine.
However, some of the names of the columns in the data frame have
special characters, accents, and such.
How do I get around this on a basic keyboard, please?
Thanks,
Erin

time difference
Dear R People:
I am looking at the ctime attribute of two different files. It
contains the year, month, day, time of creation and time zone.
Is there a way to determine the difference between the ctimes of two
files, please?
I looked in the chron package and nothing seemed to work.
Thanks in advance,
Sincerely,
Erin

FW: Time Series
Hello!
What is the error message, please?
At first glance, you are using the "ts" function. That doesn't work for
hourly frequency.
You may want to create a zoo object.
This is Round One.

calculating seconds
Dear R People:
I'm looking at some data which has the time in seconds since 1992/10/8,
15:15:42.5
Are there any functions currently available to "translate" this or should I
just do my own?
I figured that I'd check first.
Thanks,

r-package-devel is probably a better place to post this, especially if
you do not get a satisfactory reply here. This list is about R

date conversion
Dear R People:
I have a monthly time series which runs from January 1998 to December 2010.
When I use tsp I get the following:
> tsp(ibm$ts)
[1] 1998.000 2010.917 12.000
Is there an easy way to convert this to a seq.Date object, please?
I would like to have something to the effect of
1998/01/01 .... 2010/12/01
Thanks,
Erin

Hi,
If you are using roxygen-style function documentation then why not use devtools::document()?

R on an iPad
Dear R People:
Is it possible to run R on an iPad, please?
For some reason, I'm thinking that you can't have Fortran, C, etc., so
you can't do it.
But I thought I would check anyway.
Thanks,

Problem with compiling OpenBLAS to work with R
I believe that repo just follows the directions on my blog. Without seeing
Dr. Hodges?s code, my initial concern is the many references to Cygwin. My
method specifically does not use Cygwin but MSYS2 and Mingw64/Rtools35.
That will likely change to solely Rtools40 once R3.6 is released due to the
Msys system being built in to it.
There may be some library conflicts between Cygwin and

Building R from source with the PGI compiler
Hello
I would like to build R from source and use the PGI compiler, rather than
the GCC compiler.
I saw the instructions for the Intel compiler in the R Installation Manual,
but I didn't see the PGI. I tried a few times without instructions, but
without success.
Any suggestions would be most welcome. Also, I hope this is the right
group for the question.
Sincerely,
Erin

How would I do this, please?

lam vs. openmpi
Dear R Debian Users:
I wrote a quick C program (eventually to become R code) and compiled it as:
mpicc -o greet greet.c
So far so good. Now when I run mpirun, this happens:

It seems that there is no lamd running on the host erin-laptop.
This indicates that the LAM/MPI
