similar to: doing many commands within R

Dear all, Thanks to those 3 people who sent me answers to my question. Got the problem solved. Great! Now, another question of mine is: I would like to run an R script from the Linux prompt. Is there any way possible to do this? The reason is, the calculation that I'm doing takes a few hours, and I would like to automatize it. Or does it mean that I have to run source within the R

Hello veeryone, I nedd some help here. The problem is I was trying to install R on my Irix system, with little success: I got the following ugly error messages: watch out: begin installing recommended package mgcv Cannot create directory "": No such file or directory * Installing *source* package 'mgcv' ... ** libs gmake[3]: Entering directory

I want to generate a list (called "dataList" below) where each of its levels is named. These names are assigned to nameList, which contains all possible permutations of size two taking letters from a larger alphabet, e.g., "aa",...,"Fd",..,"Z1",... One of these permutations is the character string "NA". It seems that when I try to name one

hello, how can take the string in the data frame. right now i have a table that create as a data frame and stored in the file called "data.xls" and now i want to read data frame as a table in my another r program, i used the following command: the first column of the data frame is just one number called "num", but the second one a list of string, called "name". d

I am trying to define subset operator for a reference class and hitting some problem i am unable to diagnose.To give an example, here is a toy class generator that is a wrapper around a list tmpGEN<-setRefClass("TMP", fields=list( namelist="list" )) tmpGEN$methods('add'=function(obj, name){ namelist[[name]]<<-obj })

Hi, I noticed that brctl (or more accurately, libbridge) is using the wrong path when doing various lookups in sysfs: e.g. /sys/class/net/brXXX/stp_state when it should use /sys/class/net/brXXX/bridge/stp_state. This doesn't cause any problems on most systems as it falls back to the ioctl when the sysfs attempt fails; however the ioctl method is apparently deprecated. I believe the

summary: The function 'by' inconsistently strips class from the data to which it is applied. quick reason: tapply strips class when simplify is set to TRUE (the default) due to the class stripping behaviour of unlist. quick answer: This can be fixed by invoking tapply with simplify=FALSE, or changing tapply to use do.call(c instead of unlist executable example:

First, here's the problem I'm working on so you understand the context. I have a data frame of travel activity characteristics with 70,000+ records. These activities are identified by unique chain numbers. (Activities are part of trip chains.) There are 17,500 chains. I use the chain numbers as factors to split various data fields into lists of chain characteristics with each element of

The function tapply is not working in the Windows version of R=20 (Version 0.50 Beta (Sept 29, 1997)) In tapply <- function (x, INDEX, FUN=3DNULL, simplify=3DTRUE, ...)=20 ... The part: if (simplify && all(unlist(lapply(ans, length)) =3D=3D 1)) { ans <- unlist(ans, recursive =3D FALSE) names(ans)<-namelist[[1]] return(ans) } should be replaced by if (simplify

Hi all, I am using R to extract data on a regular basis. However, sometimes using the same script and the same data I am getting different observation. The library I am using and how I am reading it is as follows. library(stringr) namelist <- file("Adress1.txt",encoding="ISO-8859-1") Name <- read.fwf(namelist, colClasses="character",

Hello, These are implementations of strverscmp, scandir, alphasort and versionsort, and some test cases for them.

You need to provide reproducible data. What does the file contain? Why are you using 'sep=' when reading fixed format. You might be able to attach the '.txt' to your email to help with the problem. Also you did not state what the differences that you are seeing. So help us out here. Jim Holtman Data Munger Guru What is the problem that you are trying to solve? Tell me what

I really appreciate all your responses on this. I might not have fixed it by looking at samba logs but i noticed there was directory in user unix directory with wildcard * as folder name once i removed it, samba showed up all the files and directory. am not sure what would * as folder name caused this behaviour may be samba was trying to interpret * as something else not sure...... or it was

Hi community, I want to count the occurrence of values within a dataframe. data$names is a list of many names. With namelist <- unique(data$names) I get all the existing names. But the result is a factor, not a list of strings. I would then like to go trough all the names in a for-loop and count their occurrence. How do I make this? Best regards, Markus

Last week, we've talked here about "xtabs(), factors and NAs", -> https://stat.ethz.ch/pipermail/r-devel/2017-January/073621.html In the mean time, I've spent several hours on the issue and also committed changes to R-devel "in two iterations". In the case there is a *Left* hand side part to xtabs() formula, see the help page example using 'esoph', it

On a related note, the storage mode should try to match ans[[1]] (or unlist:ed and) when allocating 'ansmat' to avoid coercion and hence a full copy.
