similar to: memory footprint of readRDS()

The ratio of object size to rds file size depends on the object. Some variation is due to how header information is stored in memory and in the file but I suspect most is due to how compression works (e.g., a vector of repeated values can be compressed into a smaller file than a bunch of random bytes). f <- function (data, ...) { force(data) tf <- tempfile()

Dear all, to my astonishment data.table cannot be installed on R 3.5 Windows. When checking the package page, the Windows binary is available for download. When checking the server however, I can't seem to find data.table. Also install.packages() says the package is only available in source form and may need compilation. Compiling using Rtools 35 is no problem. Is this merely an issue of

I think you are confusing package and function here. Plus some of the R Core packages, that you mention, contain functions that should probably be replaced by functions with better implementation from packages on CRAN.

Dear all, as a follow-up to the question asked on R-package-devel (see link below): Someone sent a package to CRAN with a few problems. There's more things wrong with the submission, but one thing that really caught my eye was the following error: Warning message: running command '"C:/PROGRA~1/R/R-33~1.2/bin/x64/R" CMD BATCH --vanilla "testthat.R"

Indeed. as_date is from lubridate, but the same holds for as.Date. The output and it's interpretation should be consistent, otherwise it leads to confusion when programming. I understand that the difference exists after asking a question on Stack Overflow: https://stackoverflow.com/q/50766089/914686 This understanding is never mentioned in the documentation - that an Inf date is actually

And now I've seen I copied the wrong part of ?is.na > The default method for is.na applied to an atomic vector returns a logical vector of the same length as its argument x, containing TRUE for those elements marked NA or, for numeric or complex vectors, NaN, and FALSE otherwise. Key point being "atomic vector" here. On Sat, Jun 9, 2018 at 1:41 PM, Joris Meys <jorismeys at

I don't see the issue here. It would be helpful if people would report their sessionInfo() when reporting whether or not they see this issue.

Dear all, I asked this question on r-package-devel but Martin Maechler pointed out this was more suited on R-devel. So here it goes: per the manual, one should create and register both the S3 and a S4 method if one needs a method for an S4 class for a function using S3 dispatching. This is cumbersome, and not very optimal. I was wondering if there's a better way to do this. Currently I

To my surprise, I can confirm on Windows 10 using R 3.4.3 . As tail is not recognized by Windows cmd, I replaced with: system('powershell -nologo "& "Get-Content -Path temp.csv -Tail 1') The last line shows only 7 digits after the decimal, whereas the first have 15 digits after the decimal. I agree with Dirk though, 1.6Gb csv files are not the best way to work with

Joris, the point is that 'z' is NOT used as a predictor in the model. Therefore it should not affect predictions. Also, I find it suspicious that the error only occurs when the response variable conitains missings and 'z' is unique (I have tested several other cases to confirm this). -Mark Op vr 16 mrt. 2018 om 13:03 schreef Joris Meys <jorismeys at gmail.com>: >

Dear all, I've noticed by trying to download gz files from here : https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM907811 At the bottom one can download GSM907811.CEL.gz .

Dear dev team, I was sorry to see the announcement of Duncan about his retirement from maintaining the R Windows build and Rtools. Duncan, thank you incredibly much for your 15 years of devotion and your impressive contribution to the R community as a whole. Thinking about the future, I wondered whether there were plans for the succession of Duncan. Is it the intention to continue providing

Also, as mentioned in my https://stat.ethz.ch/pipermail/r-devel/2012-August/064739.html, when not specifying the mode argument, the default on Windows is mode = "w" *except* for certain, case-sensitive, filename extensions: if(missing(mode) && length(grep("\\.(gz|bz2|xz|tgz|zip|rda|RData)$", url))) mode <- "wb" Just like the need for mode =

Dear R-developers, In the 'lm' documentation, the '-' operator is only specified to be used with -1 (to remove the intercept from the model). However, the documentation also refers to the 'formula' help file, which indicates that it is possible to subtract any term. Indeed, the following works with no problems (the period '.' stands for 'all terms except the
