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?

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 -- Erin Hodgess Associate Professor Department of Computer and

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.

If you are writing a new package I don't see why you should restrict yourself to S3 or S4 classes. Your "new package" can certainly build on other packages. (Why not?) As I wrote in my previous email, if you are dealing with time series you might want to consider appropriate classes already defined in other packages, such as those obtained via library(fpp3) In my work, I deal with

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, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto:

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 programming, as you presumably know; your query is not.

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 -- Erin Hodgess Associate Professor Department of Computer

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.

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

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 -- Erin
