Why when I assign 0 to an element of an integer vector does the type change to numeric? Here is a particularly perplexing example: > v <- 0:10 > v [1] 0 1 2 3 4 5 6 7 8 9 10 > class(v) [1] "integer" > v[1] <- 0 > class(v) [1] "numeric" #!! > -- View this message in context:

I'd like to write some objects (eg arrays) to a log file. cat() flattens them out. I'd like them formatted as in 'print' but print only writes to stdout. Is there a simple way to achieve this result?

Suppose I have an n-diml array A and I want to extract the first "row" -- ie all elements A[1, ...] Interactively if I know 'n' I can write A[1,,,,,] with (n-1) commas. How do I do the same more generally, eg in a script? (I can think of doing this by converting A to a vector then extracting the approp elements then reshaping it to an array, but I wonder if there isn't a

Hi, I have a list of numbers (classified as a list) that contains integer(0) empty vectors. How do I convert those integer(0) into NAs? Thanks [[alternative HTML version deleted]]

Can someone please give me a clue how to 're'write this so I dont need to use loops. a<-ts(matrix(c(1,1,1,10,10,10,20,20,20),nrow=3),names=c('var1','var2','var3')) b<-ts(matrix(c(2,2,2,11,11,11,21,21,21),nrow=3),names=c('var1','var2','var3'))

When operating in daemon mode, will rsync check to see which file is newer and decide which direction to transfer based on that? Example, We have 2 terminal servers, A and B. I want users to be able to work on either server and have their home directories on both stay in sync. If a user logs into server A and changes files, the server would know to transfer the file from A to B. If they log

I've asked about custom sorting before and it appears that -- in terms of a user-defined order -- it can only be done either by defining a custom class or using various tricks with "order" Just wondering if anyone has a clever way to order "vintages" of the form 2002, 2003H1, 2003H2, 2004, 2005Q1, 2005Q2, etc some have H1 or H2, some have Q1,Q2,Q3,Q4, some are just plain

I'm sure I'm missing something obvious but I'm not seeing how to simply "vectorize" a function of two or more variables. Say I have f <- function(x,y) if (x>0) y else -y Now I have vectors x and y of equal length and I'd like to apply f element-wise. I.e. conceptually z <- f(x,y) where x, y, z are vectors of the same length Some magic involving apply?

When I do dev.new(), the resulting window comes to the front and grabs the focus. Is there a way to prevent this so I can continue working in other windows while the graphics are being produced?

Hello, I'm starting working myself in the use of R, reading M. J. Crawley, The R Book. The problem I do encounter is concerning the commands apropos and find: > apropos(edit) Fehler: is.character(what) is not TRUE > find(edit) Fehler: is.character(what) is not TRUE I get the same error message typing anything else instead of "edit". The command ?edit seems to work well.

I'm trying to build up a list of data.frames by "appending" one by one. If x,y,z are data.frames, I can do somelist <- list(x, y, z) (or even somelist <- list(x=x, y=y, z=z) to get names) But if I start with somelist <- list(x,y) and now want to go from this to list(x,y,z) I'm stuck. I've tried append(somelist, z) c(somelist, z) list(somelist, z) Each gives

Hello all, I've had the following apropos alternative in my ~/.Rprofile for some time, and have found it more useful than the current version. Basically, my version ignores case when searching. If others find this useful, perhaps apropos could be suitably patched (and I'd be willing to create such a patch). + seth Here is my version of apropos: APROPOS <- function (what, where =

The old apropos started with: if (!is.character(what)) what <- as.character(substitute(what)) The new one has: if (character.only) stopifnot(is.character(what)) else what <- as.character(substitute(what)) i.e., the check for is.character(what) is missing. This has the effect that 'what' can no longer be a character string generated by a function call

Is there any way to search a column of a table? I read in a table and I want to create a subset based on the criteria that a certain column (filled with words) has a word which starts with a certain letter. The only method I have seen that searches this way is apropos(), but that doesn't seem to search the location I want. If anyone can make a recommendation I would appreciate it.

Some time ago I tried to find out how to compute remainders in R. I now know that it is done with %%, which is documented in help('+'), but before someone told me that I tried: help('remainder'), help.search('remainder'), apropos('remainder') help('modulo'), help.search('modulo'), and apropos('modulo') all of which yielded nothing. I then

A further improvement to apropos() would be to sort the output. Currently, the output of apropos is in the order found on the search list and this will rarely be useful to the user. All that is needed is a sort(x) at the end of the function. + seth -- Seth Falcon | Computational Biology | Fred Hutchinson Cancer Research Center http://bioconductor.org

Dear list, Is there any functionality in R that would allow me to parse config files? I have trie ??config and apropos('config') without succes, and also search the R package site. Mvh. Marie [[alternative HTML version deleted]]
