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

thanks Loris you are bering so helpful! So, i have done what you explained, but the RDS package that runs ?using or through? R is now just closing each time i open it. I have googled and seen that i need to to the following: Tips: The recent updates to the Apple Mac OS (Sierra and High Sierra) have reorganized the ways apps, like RDS Analyst, work. So sometimes RDS Analyst will not be

Hi everybody, I have trouble installing my own package under R 2.1.0 (it is fine under R 2.0.1). My OS is Windows NT. I installed my package 'mag' by using menu "Packages/Install package from local zip files....". It's fine (html package description was updated). But when I typed in library(mag) it gave me error: Error in library(mag) : there is no package called

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?

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/.

I've encountered this note in checking packages with the latest R-devel. Googling finds it only in other package checks; searching the source tree finds in src/library/tools/R/sotools.R , but I'm not sure what it's doing there. 'symbols.rds' shows up in the SVN log here: r58591 | ripley | 2012-03-05 07:25:58 -0500 (Mon, 05 Mar 2012) | 1 line treat non-symbols.rds reports on

Hi. I'm on Windows 7 64-bit with latest R devel with and Rtools (2.16.0.1926). When I try to enable spell checking for 'R CMD check' by setting environment variable '_R_CHECK_CRAN_INCOMING_USE_ASPELL_' to 'true', I get: * checking CRAN incoming feasibility ...Warning in aspell(files, filter = "dcf", control = control, encoding = encoding, : The

Dear R-help, I have a loop, which is set to take about 26 hours to run at the rate it's going - this is ridiculous and I really need your help to find a more efficient way of loading up my array gpcc.array: #My data is stored in a table format with all the data in one long column #running though every longitute, for every latitude, for every year. The #original data is sotred as

Dear R-help community, I have looked on the R search site and archives but cannot find mention of a way of interpolating a gaussian distribution of data to a standard 2.5 degree grid. I have two global dataset and I need to correlate - unfortunately one is a 2.5 degree grid dim[longitude=144,latitude=72] and one is gaussian dim[longitude=192,latitude=94]. I would rally appreciate hearing

Dear R-community, I am looking for some simple advice - I have a matrix (therefore 2 dimensional) of global temperature. Having read R-help I think that when I ask R to image() or levelplot() my matrix will it actually appear upside down - I think I therefore need to use the line: > levelplot(temperature.matrix[,ncol(output.temp):1], ........) to get it looking like it was on the globe due

Dear R-help, Which random number generator function would you recommend for simply picking 15 random numbers from the sequence 0-42? I want to use replacement (so that the same number could potentially be picked more than once). I have read the R-help archives and the statistics and computing book on modern Applied statistics with S but the advice seems to be for much form complicated

Dear R-Help community, I am trying to overlay a single contour line over a correlation plot using levelplot in the lattice package. These are the two arrays: 1) a correlation plot over Africa - so each grid square is a different colour dependent on correlation - this is in an array: result_cor with dim[465,465] 2) a single contour line from a ***different data source*** - this is from data

Dear R-help community I am trying to write an R object (data.out) to a file in order to re-access it later and not have to re-load up the array with data every time. Here is the form of data.out > data.out <- list(lats=seq(88.542, -88.542, length=94), lons=seq(0, 360-1.875, length=192), date=vector(length=nyr*12), data=array(NA, c(nyr*12, 94*192)) ) I tried >

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

Dear R-Help friends, I am unable to get the latest version of R (2.4.1) to compile on my solaris 10 system - has anybody else experienced this problem and are you able to offer me any advice? I appreciate your time, many thanks, Jenny Barnes Here are my CURRENT specifications: platform sparc-sun-solaris2.10 arch sparc os solaris2.10

This change poses difficulties for automated build systems such as travis-ci, which is widely used in the R community. In particular because this is a WARNING and not a NOTE this causes all R-devel builds with vignettes to fail, as the default settings fail the build if R CMD check issues a WARNING. The simplest change would be for R-core to change this message to be a NOTE rather than a WARNING,
