Hi all, Is there any chance that readRDS and saveRDS might one day become read.rds and write.rds? That would make them more consistent with the other reading and writing functions.

The documentation for recordPlot says the following: > As of R 3.3.0, it is possible (again) to replay a plot from another R session using, for example, saveRDS and readRDS. However, I haven't been able to save and restore a plot displaylist and have it work within the same R session, using R 3.4.3 or 3.3.3. Here's an example: # Save displaylist for a simple plot

I hardly know anything about the format used in (non-compressed) serialization/RDS, but hoping someone with more knowledge could give me some feedback; Consider two R processes running in parallel on the same unknown file system. Both of them write and read to the same RDS file foo.rds (without compression) at random times using saveRDS(object, file="foo.rds", compress=FALSE) and

Hello, I looked in the R-help but could not find an archive addressing the following. I would like to convert a character to numeric after reading a file with RDS extension. After using as.numeric, I checked if it is numeric. It was not converted. Please help. Here is my code >Report <- readRDS(file="RDS/Report.RDS") > Report[1:2,] dive_id date

Dear all I was thinking about efficient reading data into R and tried several ways to test if load(file.Rdata) or readRDS(file.rds) is faster. The files file.Rdata and file.rds contain the same data, the first created with save(d, ' file.Rdata', compress=F) and the second with saveRDS(d, ' file.rds', compress=F). First I used the function microbenchmark() and was a astonished

Note that if you force a garbage collection each iteration the times are more stable. However, on the average it is faster to let the garbage collector decide when to leap into action. mb_gc <- microbenchmark::microbenchmark(gc(), { x <- as.list(sin(1:5e5)); x <- unlist(x) / cos(1:5e5) ; sum(x) }, times=1000, control=list(order="inorder")) with(mb_gc,

The large value for maximum time may be due to garbage collection, which happens periodically. E.g., try the following, where the unlist(as.list()) creates a lot of garbage. I get a very large time every 102 or 51 iterations and a moderately large time more often mb <- microbenchmark::microbenchmark({ x <- as.list(sin(1:5e5)); x <- unlist(x) / cos(1:5e5) ; sum(x) }, times=1000)

Hi there Thanks for your answers. I didn't expect that this would be so complex. Honestly, I don't understand everything you wrote since I'm not an IT specialist. But I read something that reading *.rds files is faster than loading *.Rdata and I wanted to proof that for my system and R version. But thanks anyway for your time.

Caching happens, both within the operating system and within the C standard library. Ostensibly the intent for those caches is to help performance, but you are right that different low-level caching algorithms can be a poor match for specific application level use cases such as copying files or parsing text syntax. However, the OS and even the specific file system drivers (e.g. ext4 on flash disk

Not convinced Jeff is completely right about this not concerning R, since I've found that the application language (R, perl, etc.) makes a difference in how files are accessed by/to OS. He is certainly correct that OS (and versions) are where the actual reading and writing happens, but sometimes the call to those can be inefficient. (Sorry, I've not got examples specifically for file

Dear List: I'm having the same problem that was reported recently. The latest version of R cannot load the Matrix package, even though it is installed and readable. I've read the archive files for this list and tried the suggested solutions (e.g., removing/uninstalling the Matrix package and reinstalling it). Nothing has worked so far. Does anybody have advice of what I could try next?

Dear Ubunutu R users, Vincent Goulet and myself would like to announce the availability of R 2.11.0 for Ubuntu's latest release, Lucid Lynx. The packages should be on or arriving soon to your favorite mirror. R 2.11.0 packages also exist on CRAN for all Ubuntu releases going back to hardy. As Johannes Ranke pointed out for the Debian release, R packages installed under R < 2.10.0

I am trying to add Michael Rutter's ppa to my repository.? I cannot do this from the command line.? I think I may be behind a firewall so copying the key to a text file is my best option.? When I search for the key at http://keyserver.ubuntu.com:11371/ the search fails. Tried typing and cutting and pasting E084DAB9 into the search box without success. How can I get the key?
