similar to: Error in data.frame(srcfile = NA_character_ ...) using R CMD check

Hi Mr Tierney, I have noticed an error message from R 1.12.x's CMD check for a while (apparently prof Ripley completely rewrote CMD check in R 1.12+) e.g.: http://bioconductor.org/checkResults/2.7/bioc-LATEST/snpMatrix/lamb2-checksrc.html ---------------- * checking R code for possible problems ... NOTE Warning: non-unique value when setting 'row.names': ?new? Error in

I've been searching for patterns in why some POSIXlt objects have the zone and gmtoff components and some don't and why gmtoff is sometimes NA when the zone is known. Is there a pattern or is it just that the additional fields and workarounds were added in an ad hoc way? E.g., as.POSIXlt adds the zone and gmtoff components for all strings and logical NA inputs if the time zone is not

Astute observation. And of course we should be passing integer when we use %d. It's an edge case in how we printed ITime objects in data.table: On Tue, May 23, 2017 at 11:53 AM, Joris Meys <jorismeys at gmail.com> wrote: > I initially thought this is "documented behaviour". ?sprintf says: > > Numeric variables with __exactly integer__ values will be coerced to >

Yes, what Joris posts about is exactly what I noted in my March 9th post to R-devel. The behaviour is sort of documented, but not in the clearest manner (in my opinion). Like I say, my ultimate conclusion was that the silent coercion of numerics to integers by sprintf() was a handy convenience, but not one that should be relied about to always work predictably.

Hello, I'm writing a package am running 'R CMD check' on it. Is there any way to make 'R CMD check' not warn about a missmatch between 'NA_character_' (in the function definition) and 'NA' (in the documentation)? Thanks for any help. Sincerely, Joh

Hi, I'm trying to understand whether the new source file references can help me with something I want to do. Let's say I have foo <- parse(text = " a <- 1; b <- 2**2 a + b ") I now wish to recover the sources for the parsed expressions. I can get them one at a time: > foo[[2]] b <- 2^2 > as.character(attr(foo, "srcref")[[2]]) [1] "b <-

So, to summarize, the open questions are: (1) Should as.complex(NA_character_) give complex(r=NA_real_, i=0) instead of NA_complex_? (2) Should the first argument in c(NA, x) and c(NA_integer_, x), where typeof(x) == "complex", be promoted to complex(r=NA_real_, i=0) instead of NA_complex_? My opinions: (1) No. The imaginary part of the

I initially thought this is "documented behaviour". ?sprintf says: Numeric variables with __exactly integer__ values will be coerced to integer. (emphasis mine). Turns out this only works when the first value is numeric and not NA, as shown by the following example: > sprintf("%d", as.numeric(c(NA,1))) Error in sprintf("%d", as.numeric(c(NA, 1))) : invalid

Hi, I have discovered that sample() fails with an uninformative error message when the x argument is a single NA of type double or integer. I can reproduce the problem with the following code: base::sample(NA) # NA is of logical type above base::sample(NA_character_) base::sample(NA_complex_) base::sample(NA_real_) base::sample(NA_integer_) The last two lines throw the following error: Error

https://github.com/Rdatatable/data.table/issues/2171 The fix was easy, it's just surprising to see the behavior change almost on a whim. Just wanted to point it out in case this is unknown behavior, but Evan seems to have found this as well.

According to http://cran.r-project.org/doc/manuals/r-release/R-lang.html#Reserved-words if else repeat while function for in next break TRUE FALSE NULL Inf NaN NA NA_integer_ NA_real_ NA_complex_ NA_character_ ... ..1 ..2 etc. are all reserved keywords. However, in R 3.0.2 you can do things like: `if` <- function(cond, val1, val2) val2 after which if(TRUE) 1 else 2 returns 2.

Hello, Two lapply questions (system info and sample data below): 1) Why does the first form of command1 add the name of y _after_ the str() output rather than before as does the second (preferred) form? # command1 version1 invisible(lapply(ls(pattern='bn'), function(y) cat(y, "\n", str(get(y)), "\n") )) # command1 version2 (preferred output)

Hi I'm trying to extract complete rows from a dataframe by group based on the maximum in a column within that group. Thus I have a dataframe: cvd_basestudy ... es_time ... _____________ study1 ... 0.3091667 study2 ... 0.3091667 study2 ... 0.2625000 study3 ... 0.3033333 study3 ... 0.2625000 __________ etc I can extract the basestudy and the max(es_time)

I am trying to set up a data set for a survival analysis with time-varying covariates.

This is what I have now: ID Age DaysEnrolled HAZ WAZ WHZ Food onARV
