Doing help("R_LIBS") brings up a help file (the same one as help(library)), but the help file doesn't mention R_LIBS. It does have a link to .libPaths, which does document R_LIBS. The quickest fix would be for help("R_LIBS") to bring up the .libPaths help file. --please do not edit the information below-- Version: platform = i386-pc-mingw32 arch = i386 os = mingw32

I saw the following in R help page "Extract.data.frame". The replacement methods can be used to add whole column(s) by specifying non-existent column(s), in which case the column(s) are added at the right-hand edge of the data frame and numerical indices must be contiguous to existing indices. On the other hand, rows can be added at any row after the current

Full_Name: Steven McKinney Version: 2.9.0 OS: Mac OS X 10.5.6 Submission from: (NULL) (142.103.207.10) A corrupt data frame can be constructed as follows: foo <- matrix(1:12, nrow = 3) bar <- data.frame(foo) bar$NewCol <- foo[foo[, 1] == 4, 4] bar lapply(bar, length) > foo <- matrix(1:12, nrow = 3) > bar <- data.frame(foo) > bar$NewCol <- foo[foo[, 1] == 4, 4]

I'm trying: R CMD Rdconv file.Rd --type=Ssgm If file.Rd contains \code{x} then this is currently translated as <s-expression>x</s-expression> I suggest instead translating to <code>x</code> (provided that R CMD Sd2Rd is changed to support the <code> tag; I just submitted that bug separately). Note that this is an enhancement, not a bug. This change would

Hi Everyone, I'm trying to write selfStart non-linear models for use with nls. In these models some combinations of parameter values are illegal; the function value is undefined. That's OK when calling the function directly [e.g. SSmodel(x, pars...)]; I return an appropriate non-value such as NA or Inf. However, when called from nls [e.g. nls(y~SSmodel(x, pars...), ...)] those

I'm trying to step through some code using browser(), executing one line at a time. Unfortunately, whenever I execute a comment line, the browser exits. I previously reported a similar problem with blank lines. These problems are a strong incentive to write poor code -- uncommented code with no blank lines to improve readability -- so that I can use browser() without it exiting at

Dear List, I have a list of 600+ *.gz files that I would like to extract and read the geotiffs contained within them. I tried using the untar() function to simplify this task but I am stumped by an error. I've combed the Internet for a solution without luck. The details are below, and any help in solving this matter is appreciated. > files = list.files(path = "J:/GIMMS/NDVI",

Dear list, When using as.POSIXlt with times measured down to microseconds the default format.POSIXlt seems to cause some possibly undesirable behaviour: According to the code in format.POSIXlt the maximum accuracy of printing fractional seconds is 1 microsecond, but if I do; options( digits.secs = 6 ) as.POSIXlt( 1.000002 , tz="", origin="1970-01-01") as.POSIXlt( 1.999998 ,

The problem first appeared in R 2.6.1 and is still there in R 2.6.2 On Windows running R CMD check command for glmpath package fails. The reason seems to be that when R is running the examples file (glmpath-Ex.R), it skips about 50 lines and as a result gives a syntax error. I'm working with a modified version of the CRAN glmpath 0.94. My version happens to give a more clear example of a

Not sure why the data.frame function does not capture the name of the column field when its being built with only one column.

Hi all, I was just radomly playing with R and got the following error when trying to filter a data frame using a string: > Angel <- c(7,8,6,9,10) > Buffy <- c(8,9,4,9,10) > Firefly <- c(9,9,10,10,10) > DrHorrible <- c(10,9,9,10,10) > my.df <- data.frame(Angel, Buffy, Firefly, DrHorrible) > my.df["DrHorrible"] DrHorrible 1 10 2 9 3

I obviously don't know what I'm doing. I want to create "ByEBNum" as a data frame, but it comes out as a list. How do I make it a data frame? > EBNumStn <- c(673.65, 800, 1000, 1000, 800, 700, 600, 500, 400, 200, 50, 50 ) > ByEBNum <- data.frame(c(1:12),EBNumStn) > typeof(EBNumStn) [1] "double" > typeof(c(1:12)) [1]

Some suggestions for R-intro: -------------------------------------------------- Section 9.2.2, change: (Note the function split() which produces a list of vectors obtained by splitting a larger vector according to the classes specified by a factor. This is a useful function, mostly used in connection with boxplots. See the help facility for further details.) Warning: for() loops are used in

Folks: Problem: [<-.data,frame() is losing attributes under certain curcumstances shown below. I think this is a bug, at least in documentation, as I was unable to find explicit documentation of the behavior. Indeed, the only documentation I found told me attributes are preserved. Here is a detailed description: > df <- data.frame(a=1:3, b=letters[1:3]) > attr(df,"foo")

Suppose I have the following function myFun <- function(formula, data){ f <- formula(formula) dat <- model.frame(f, data) dat } Applying it with this sample data yields a new dataframe: qqq <- data.frame(grade = c(3, NA, 3,4,5,5,4,3), score = rnorm(8), idVar = c(1:8)) dat <- myFun(score ~ grade, qqq) However, what I would like is for the resulting dataframe (dat) to include
