I seem to have a problem getting latex (Hmisc) to work. Any suggestions as to what I am doing wrong? Thanks library(Hmisc) aa <- data.frame(aa=1:10, bb=rnorm(10, 5, 2), cc=rnorm(10, 20, 4)) rr <- lm(cc~aa+bb, data=aa); rr latex(rr) > latex(rr) 'latex' is not recognized as an internal or external command, operable program or batch file.

Clearly, I don't understand what order() is doing and as ususl the help for order seems to only confuse me more. For some reason I just don't follow the examples there. I must be missing something about the data frame sort there but what? I originally wanted to reverse-order my data frame df1 (see below) by aa (a factor) but since this was not working I decided to simplify and order by

I have just started using ggplot2 and I seem to be doing something stupid in writing ggplot2 commands on more than one line. In the example below the commands on one line are working fine, but as soon as I put them on two lines I get an error. Can any one point out what I am doing wrong? It must be something blindingly simple. Thanks Example

Hi, I've been trying to convert numbers from an online temperature database into dates and time that R recognizes. I've tried as.Date, as.POSIXlt and strptime the problem is that the database has put a T between the numbers and R will not accept any conversions. currently it sees the date as a factor with the format as 1981-01-02T08:00I would like to keep only the year and month, but my

Hello! I've been trying to get this right for quite a while now and fear there is an easy solution I just don't see. I did not have this problem in Linux, and I searched r-help and Google but did not find a solution, but of course I am grateful for and resources I might not have found our not understood yet. I try to parse a time stamp with time zone. I essentially just want to parse the

Dear All, I am trying to convert to POSIXct after pasting a date and a time in character format with strptime. It is probably obvious but I don't understand why I get an error message after bsamp$spltime<-strptime(test,format="%d-%B-%y %H:%M") whereas I can get what I want if I do it in 2 steps and rbinding ? Thanks and best regards, Jean-Louis This is the R console output

> is.na(strptime("5/2/1992", format="%m/%d/%Y")) [1] FALSE > is.na(strptime("5/3/1992", format="%m/%d/%Y")) [1] TRUE Any idea what's going on with this? Running strptime against all dates from around 1946, only 5/3/1992 was converted as "NA". Even stranger, it still seems to have a value associated with it (even though is.na thinks

Hi all, I am noticing some strange behaviour so I am bringing to this list. In the past when I have submitted bugs to bugzilla, I have come here first for confirmation/advice. Hopefully this is appropriate. Upgrading from R 3.5.2 to R 3.5.3 seems to have elicited some strange behaviour on my Windows machine. R seems to have trouble spawning a new process on my machine. You can noticing with all

My day for dumb questions. How do I increase the type size in the Rgui console in Windows? (R-2.13.0, Windows 7) It looked to me that I just needed to change the font spec in Rconsole but that does not seem to be working. The R FAQ for Windows has a reference in Q3.4 to changing fonts, (Q5.2), but I don't see anything relevant there. Rconsole originally was: font = TT Courier New points =

Hello, Two lapply questions (system info and sample data below): 1) Why does the first form of command1 add the name of y _after_ the str() output rather than before as does the second (preferred) form? # command1 version1 invisible(lapply(ls(pattern='bn'), function(y) cat(y, "\n", str(get(y)), "\n") )) # command1 version2 (preferred output)

R Gurus: This sounds not a FAQ. I upgraded WinEdt from 5.4 to 5.5 , following load RWinEdt, R-WinEdt editor appears.

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

Dear all, I am working on an R package intended for CRAN that requires Tcl version 8.6 because of the TclOO tcl extension and the -angle option for canvas text items. R for Windows currently still ships with Tcl 8.5. Does anyone have experience with linking R under Windows to a Tcl interpreter of version 8.6? When I link R 3.2.2 (installed from the binary on Windows 8) to a custom Tcl

In the latest R 2.8 alpha for Win32, if either of the commands are typed: > help("erfc") .. or .. > ?erfc the result is: No documentation for 'erfc' in specified packages and libraries: you could try '??erfc' This should be: 'help.search("erfc")', as shown in R 2.7.2 Apologies if this has already been submitted/fixed. -Mike --please do not edit

Hello, I have just installed R 2.7.0 and re-installed SciViews 0.8-9 and Tinn-R 1.19.4.7 and seem to have broken something along the way as follows. I double-click on my current .RData file in the Windoze explorer, R Console and Tinn-R load successfully (?). I can list objects in my working directory with ls() but, when I attempt to refresh any list in the R explorer tab of the Tools child

I realize that R-core must be busy with the imminent release of 2.11.0, so please consider this not urgent. The NEWS file for 2.12.0 (Windows-specific) says, in part: For now, 32-bit packages with compiled code built under 2.{10,11}.x can be used, but this will be disabled before release. For me, this doesn't work without a tweak. For example, > library(mvtnorm) #Error:
