[Rd] issue with promises for time parameter of rep()
Greetings,
The following is based on a question I raised on Stackoverflow:
https://stackoverflow.com/questions/46280120/calling-printls-str-in-function-affect-behavior-of-rep/46283979#46283979
Start a new R session with an empty Global Env. Then define:
f <- function(n) {
print(ls.str())
rep("hello", times = n)
}
Now run:
f(x)
Instead of getting the expected "object 'x' not found" error, you get:
n : [1] "hello"
It was suggested that I file the issue here as a possible bug.
Regards,
Homer

Re: [Rd] issue with promises for time parameter of rep()
Here is the same issue with closures:
g <- function(n) {
missing(n)
}
f <- function(n, force) {
if (force) {
tryCatch(n, error = function(...) NULL)
}
g(n)
}
g(`_x`)
#> [1] FALSE
f(`_x`, force = FALSE)
#> [1] FALSE
f(`_x`, force = TRUE)
#> [1] TRUE

[Rd] R and Visual Studio
Hi, I am trying to build R using Visual Studio 2010 but without success. My question is if it possible build R with this compiler anyway? If not, could someone please tell how to link one's C code against both the static and shared libraries of R for Windows (that comes from the official website found here https://cran.r-project.org/mirrors.html)? Thank you! __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

By reading the Fine Manuals that came with your version of R, in particular 'R Installation and Administration' and 'Writing R Extensions'. You will need to install Rtools which provides the compiler R uses on Windows.

[Rd] what do you think about write.table(... qmethod = "excel")?
Last week one of our clients reported trouble with a csv file I generated with write.table. He said that columns with quotes for character variables were rejected by their data importer, which was revised to match the way Microsoft Excel uses quotation marks in character variables. I explained to them that quoted character variables are virtuous and wise, of course, but they say Microsoft Excel CSV export no longer quotes characters unless they include commas in the values. They showed me a CSV file from Excel that looked like this x1,x2,x3,x4 5 6 fred,barney,betty,x bambam,"fred,wilma",pebbles,y Note how the quotes only happen on row 2 column 2. I was surprised it did that, but now I have some pressure to write a csv maker that has that structure. Its weird, even when there are spaces in values there are no quotation marks. Has anybody done this and verified that it matches CSV from MS Excel? If I succeed will you consider a patch? pj -- Paul E.

Re: [Rd] issue with promises for time parameter of rep()
Thanks. Fixed in R-devel and R-patched. This now gives
f <- function(n) {
print(ls.str())
rep("hello", times = n)
}
f(n)
## n :
## Error in f(n) : object 'n' not found
## In addition: Warning message:
## In f(n) : restarting interrupted promise evaluation
Best,
luke

The only difference is that between calls one and two, I removed the stray
"5 6"
from the first line.

It really makes no sense to write a .csv parser that _only_ supports .csv files created by Excel. If you're going to use Excel as a model, a more sensible approach would be to write a csv parser that supports all the formats that Excel itself supports; Excel of course has no problem importing "x1","x2","x3","x4" "fred","barney","betty","x" "bambam","fred,wilma","pebbles","y" So, seriously, tell them to just fix their csv parser. Since they seem hung up on Excel, it may help to point out that it does in fact import csv produced by write.csv without complaint.

That depends on whether this is a paying client or not. > It really makes no sense to write a .csv parser that _only_ supports .csv files created by Excel. That's true, but if that's what they want to do, and they're willing to pay to be able to write files that imitate Excel, then why not do what they ask? On the other hand, if they aren't willing to pay for the work, then you should lecture them on how silly their request is. In any case, base R functions should not include nonsense, so this is not something that should go into R.
