I had occasion recently to read in a one-line *.csv file that looked like: "CandidateName","NSN","Ethnicity","dob","gender" "Smith, Mary Jane",111222333,"E","2/25/1989","F" That "F" (for female) in the last field got transformed to FALSE. Apparently read.csv (and hence read.table) are inferring

When I create a manual for a package that I create and use locally, e.g. via R CMD Rd2dvi --pdf foo where ``foo'' is the name of the directory containing the source for the package (also named ``foo'') the resulting manual does not appear to have an index. The package.pdf files appearing on CRAN all seem to have indices. What must I do to get an index appended to the

Thanks Peter. I tried running the uninstalled R; it worked. I checked on the existence of FAQ, etc. --- yep everything was there. I don't know about over-zealous virus checkers; I haven't overtly installed any such. So, mystified, I started all over again from scratch. This time it worked; seamlessly. Totally mysterious. Story of my life. Be that as it were, all systems are go

I keep getting repeated copies of ``R-help post acknowledgements'' in respect of a couple of postings that I made to the list this morning (my time). I only posted each posting *once*. I hope that others are not getting repeated copies of my postings .... I mean I *know* my postings are so wonderful they merit re-reading, but one does not need another copy in order to re-read! :-)

Is there any way to do this (test for the existence of a file) in R? In Splus (3.4) I can do unix(paste("test -r", fnm), output = F) where ``fnm'' is a character string giving the pathname of the file. This returns 0 if the file exists and 256 if it doesn't. I thought in R to do something like system(paste("test -r", fnm), intern =T) but this

(1) Is there a (simple) way of getting cloud() to do *both* type="p" and type="h"? I.e. of getting it to plot the points as points *and* drop a perpendicular line to the underlying plane? (2) Is there a way of telling cloud() to drop its lines to the floor of the bounding box, rather than to the plane z=0? I thought that the "zero.scaled" argument (for

Here is an example given from ?yags library(methods) data(stackloss) Y1 <- yags(stack.loss~Air.Flow,id=1:21, data=stackloss) How can I access parts of the output. I tried: > str(Y1) Formal class 'yagsResult' [package "yags"] with 25 slots ..@ coefficients : num [1:2] -44.13 1.02 ..@ coefnames : chr(0) > Y1$coefnames Error in Y1$coefnames : $

I was flummoxed for a long time by errors generated when I did something like install.packages(foo,lib="Rlib") where ``Rlib'' is my personalized directory of R packages, which lives in my home directory (from which I started R before issuing the foregoing install.packages() call. Recently someone (I forget who, but thanks very much to whomever it was) pointed out that I

For reasons best known only to myself ( :-) ) I wish to create a data frame with 0 rows and 9 columns. The best I've been able to come up with is: junk <- as.data.frame(matrix(0,nrow=0,ncol=9)) Is there a sexier way? cheers, Rolf ###################################################################### Attention:\ This e-mail message is privileged and confid...{{dropped:9}}

I have been trying to write a function mv(a,b) to move an object a to object b. It returns no value, but only exists for this side effect. Basically it just does b <- a; rm(a). With some checking and prompting about over-writing. The thing is, I'd like to be able to use either call by name or call by value syntax. I.e. I want to set up my argument processing so that mv(a,b)

I am trying to do a histogram lattice plot and I would like the histogram to be filled with a different colour in each panel. Note: I want every bar in each histogram to be the same colour, but that there should be different colours *between* histograms. Can't seem to get this to work. I thought that something like the following would be a goer: set.seed(42) X <- rnorm(200) A <-

I have vague recollections of seeing this question discussed on r-help previously, but I can't find the relevant postings. I want to determine (from within a given function) the name of the function calling that given function. E.g. if I have a function foo() which calls a function bar(), and also a function clyde() which calls bar(), I want to have, in the code of bar(), an instruction

I am trying to install the latest development version of R so as to be able to perform a package check according the rules specified for CRAN. I performed the following steps: (1) Downloaded R-devel.tar.gz, dated 04-Mar-2016 03:21, from CRAN (2) Upacked. (3) Created directory "BldDir" next to the directory "R-devel". (4) Changed directories to BldDir. (5) Executed

I just noticed a certain ``usage'' in a recent posting, and couldn't restrain my self from commenting. The usage was of the form ``if(X==TRUE)'' where X was a logical variable. This sort of thing is brought to you by your Department of Redundancy Department. The ``==TRUE'' bit is irrelevant, incompetent, and immaterial, as Perry Mason used to say. The value of

Dear all I was wondering whether such a long post could be fortune-ed. What do you think?

I tried to search for a string of words ``as one entity'' following the example in the help file: > RSiteSearch("{logistic regression}") and got the error message: 2008-09-11 08:55:41.356 open[823] No such file: /Users/rturner/http:/ search.r-project.org/cgi-bin/namazu.cgi?query={logistic+regression}

I'm not sure if this is the right target to which to direct this post, but I couldn't think of anything more appropriate. I just downloaded the Hmisc package to the Imac that I use. When I attempted to load it I got an error to the effect that it could not load the library: /Library/Frameworks/R.framework/Versions/2.5/Resources/lib/ libgfortran.2.dylib Note the ``2.5'' in

I have a data frame somewhat like this: myframe <- data.frame (ID=c(2,3,4,5), Hunger =c(415,452,550,318 )) myframe Now I would like to add a column to the right which summarizes the values for Hunger somewhat to reduce the number of values: If the values for Hunger are between 300-400 I would like to insert the number 350, between 400-500 insert 450 between 500-600 insert 550 Does

I stumbled across a mild glitch when trying to compare the result of gam() fitting with the result of lm() fitting. The following code demonstrates the problem: library(gam) x <- rep(1:10,10) set.seed(42) y <- rnorm(100) fit1 <- lm(y~x) fit2 <- gam(y~lo(x)) fit3 <- lm(y~factor(x)) print(anova(fit1,fit2)) # No worries. print(anova(fit1,fit3)) # Likewise. print(anova(fit2,fit3)) #

I have written a function make.fun(), which I keep in my personal ``miscellaneous'' package. It searches the current working directory for files named ``*.R'' and sources them if their modification date is later than the date stored in ``.Last.make.date''. (The variable .Last.make.date then gets updated.) The function checks whether .Last.make.date exists before
