similar to: Trouble loading "saved" Rdata

Dear list, I make use of cached objects extensively for time consuming computations and yesterday I happened to notice some very strange behavior in that respect: When I execute a given computation whose result I'd like to cache (tried both saving it as '.Rdata' and via package 'R.cache' which uses a own filetype '.Rcache'), my R session consumes about 200 MB of

On a Unix machine I ran caret::rfe using the multicore package, and I saved the resulting object using save(lm2, file = "lm2.RData"). [Reproducible example below.] When I try to load("lm2.RData") on my Windows laptop, I get Error in loadNamespace(name) : there is no package called 'multicore' I completely understand the error and I would like to ignore it and

I have date data as a numeric and hourly data in 0 to 2300 hours in a dataframe. d <- rep(20110101,24) h <- seq(from = 0, to = 2300, by = 100) df <- data.frame(LST_DATE = d, LST_TIME = h, data = rnorm(24, 0, 1)) S <- chron(dates. = as.character(df$LST_DATE), times. = paste(as.character(df$LST_TIME/100), ":0:0", sep = ""), format =

Hello. What happens in the following is that I create two simple functions, f and g, on the workspace. Then I replace g. When I then call f, it uses the old version of g. Now clearly, the circumstances for this to happen must be quite special and rare. But I'd say they're not pathological. It seems to require two things: 1) masked versions of f and g on a search position lower down the

I have a 43MB dataframe ( 5 variables) and I'm trying to summarize subsets of the data. I've RTFM ( not very clear) and looked at a variety of samples but cant seem to figure out how to make these functions work. A sample of what I want to do would be this: ids<-seq(1,50) years<-c(rep(5,10),rep(6,10),rep(7,10),rep(8,20))

Dear All, Could you please recommend how I can do this? I have several text files in one folder. Let's name them A0801.RSK, A0802.RSK, .... I would like R to 1) Know all file names in this folder 2) Update value in one column of these files 3) Write results in another text file with _xval in the file names Below is R code for read, update, and write one file

As Jeff says, it might be that you have a ~/.Rprofile file with instructions to load packages when R starts. It could also be that you have a .RData file, which is saved if you answer yes to: > Save workspace image? [y/n/c]: y when you quit R. If this file exists, then R loads it and all the objects you had when you saved it. If there are objects associated with packages, then that will

Hello, I am unable to start an R session by double-clicking on an existing .RData file from the Windoze file explorer. A dialogue appears with the message "Fatal error: unable to restore saved data in .RData", and I notice in the R Console the last few lines are: "Loading required package: R2HTML NULL error in function () : unused argument(s) (1:43)" I tried starting

Can you be more specific about what conditions cause R to automatically load a package when a .RData file is loaded? My experience has actually been the opposite.

I've just had an interesting thing happen to one of our students. He's using R 1.9.1 on Linux, and so I dont expect bugfixes, I'm just reporting this out of interest in case anyone else has had this happen. Starting R caused a seg fault shortly after "[Previously saved workspace restored]". Running "R --no-restore-data" worked fine so I suspected a corrupted

Hello All, I am working on graph object using IGRAPH package wanted to do Bonacich Power. This is my graph object.

Colleagues: I am having trouble loading data from within .Rdata file within the environment of a function. That is, the following always loads to the global environment: f1 <- function() { load("mydata.Rdata") # compute with objects from mydata.Rdata. } I wish to load mydata.Rdata only within the function f1. Perhaps I have misunderstood

Greetings and happy new year! I am in the process of converting some of the old S-PLUS scripts from Visualizing Data (Cleveland, 1993) into lattice. In fact, I did most of it several years ago, and at the time, all of the scripts that contained loess() worked fine. Tonight, I ran most of the scripts again, but every one that I tried with a loess() call crashed R. I tried it in two sessions, one

Hi developers, After some investigation I have found there can be large discrepancies in the same object being saved as an external "xx.RData" file. The immediate repercussion of this is the possible increased size of your .RData workspace for no apparent reason. The function and its three scenarios below highlight these discrepancies. Note that the object being returned is exactly

Hello. I was writing some code that computes on the language and came across this. I can work around it, but thought you might like to know about it. > f <- function(x) { NULL } > a <- as.list(f)[[1]] > a # ie print(a) Error: argument "a" is missing, with no default Note it says *argument* "a", which is strange. In fact, and unsurprisingly, the bug lies with

Dear Sir/Madam: I'm currently running R 1.9.1 on a Mac OS 10.3. I have been able to use it fine for a while now. But for some reason, it now crashes each time I open it with the error: Fatal error: unable to restore saved data in .Rdata I read on the online help forum that I can just delete the bad .Rdata file. But I cannot find it. I even tried to delete everything related to R and

Dear list, when iterating over a set of Rdata files that are loaded, analyzed and then removed from memory again, I experience a *significant* increase in an R process' memory consumption (killing the process eventually). It just seems like removing the object via |rm()| and firing |gc()| do not have any effect, so the memory consumption of each loaded R object cumulates until
