similar to: Problem reading R files

I've tried to re-experiment the tutorial presented at http://www.rdatamining.com/docs/twitter-analysis-with-r and specifically aimed to use rds files (tweet records) at http://www.rdatamining.com/data/.

Hi there, I faced a weird problem doing a seemingly simple task in R. Specifically, when trying for reading an RDS file from the working directory, the following error is appeared. Code: records <- readRDS("tweets.rds") Error: Error in readRDS("tweets.rds") : error reading from connection In addition: Warning message: In readRDS("tweets.rds") : invalid or

Wouldn't the obvious problem be that your data file is corrupted or was never created using saveRDS in the first place? Can you show us a complete example of creating and attempting to read what was just created?

Join the RDataMining project to build a comprehensive R package for data mining http://www.rdatamining.com/package We have started the RDataMining project on R-Forge to build an R package for data mining. The package will provide various functionalities for data mining, with contributions from many R users. If you have developed or will implement any data mining algorithms in R, please

Hi All I came across a problem below when doing stemming and stem completion with package tm in R. Word "mining" was stemmed to "mine" with stemDocument(), and then completed to "miners"with stemCompletion(). However, I prefer to keep "mining" intact. For stemCompletion(), the default type of completion is "prevalent", which takes the most

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.

Hi all, I maintain the package ?qrandom? which is based on a web API. In last time the testthat tests failed because the website was down. I implemented the following code in v1.2.2 to ensure that tests are only run if the website is accessible and to avoid the CRAN checks to fail: > library(testthat) > library(qrandom) > check_qrng <- function(){ > tryCatch( >

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

Hi, I am running Ubuntu 10.10 and I have just installed R 2.14.0. When I try to install a package: install.packages("SPOT") it returns an error message: "Error in readRDS(file) : error reading from the connection". Also, when I try the command in R: update.packages(), it returns the same error message described previously. Any ideas? Regards, Monica [[alternative

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

Hi all, When I run the example in RProfmem, I get: Rprofmem("Rprofmem.out", threshold=1000) example(glm) Rprofmem(NULL) noquote(readLines("Rprofmem.out", n=5)) ... [1] 1384 :5416 :5416 :1064 :1064 :"readRDS" "index.search" "example" [2] 1064 :"readRDS" "index.search" "example" [3] 4712

I finally put together the final touches on the first version of the camping-oauth gem. It allows you to make a Camping web app into an OAuth provider. It leverages ruby-oauth and the oauth-plugin. An example of a use case is a web service built with Camping (using json/xml with/without REST). You can find it on GitHub: http://bit.ly/campingoauth I also wrote a blog post on how to use it (and

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

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
