Dear all I use aggregate with variables of type numeric and dates. For type numeric functions, such as sum() are very fast, but similar simple functions, such as min() are much slower for the variables of type 'dates'. The difference gets bigger the larger the 'id' var is - but see this sample code: dts <- dates(c("02/27/92", "02/27/92",

Dear All, I am trying to convert some S-plus code that I have to run MCMC into R-code. The program works in S-plus, but runs slowly. I have managed to source the program into R. R recognizes that the program is there; for example, it will display the code when I type the function name at the prompt. However, the program will not run. When I try to run the program, I get the following error

hello all i searched the archives and couldn't get a solution to the following question. i have the following function: F=function(z,v) { if (v==-.5) return(1) else return(2*v/z + 1/Recall(z,v-1)) } and while testing whether it works (ie F(z,v) is approx = besselK(z,1+v)/besselK(z,V). the recursion formula allows one to calculate besselK(z,1+v)/besselK(z,V) for large values of z )

Hi I'm encountering an error with some of my Windows clients when using CTDB and samba to access a GPFS hosted share. We see the following error all the time.

All the timestamps seem reasonable for the data copied. The GPFS

Hi. I am trying to get data from mysql database using a couple of queries. I do one query to find out the indexes. Then i need to use these indexes in another query, but i keep getting errors. Here is something: numb <- dbSendQuery(con2, "select distinct(comparison) from table1") count <- fetch(numb, -1) my.matrix <- as.matrix(count) rs <- dbSendQuery(con2, "select

Dear R-list, I am having troubles selecting rows from a very large data-set containing distances between capitals.

tags 516774 = patch tags 516294 = upstream thanks Hi! Please find attached a diff closing #516774 by adding mkstemp(3), again with a minimalistic pseudo-arc4random(3) behind it. I?ve revisited the code. An mkstemp testsuite from the ?net shows it works, except for not caring how many ?X?en are in the template. Addressing #516294, it allows compiling and linking an mksh from today?s CVS against

Hi, I've been working on ogg123 to see if i could add a remote interface compatible with the one in mpg123. This remote interface is used mainly by mp3 players which use mpg123 as their backend. The reason i did this was that i have recently encoded some of my cd's in ogg vorbis format but wanted to keep using my favourite player (playmp3list,

Hi All, just a quick (?) question while I wait my code runs... I'm comparing the identity of the lines of a dataframe, doing all possible pairwise comparisons. In doing so I use identical(), but that's by the way. I'm doing a (not so) quick and dirty check, and subsetting the data as data[row.numb,] and data[a different row,] I suspect the problem there is that I load into

Dear All, since years I am struggling with Surv objects in data.frames. The following seems to have to do with it. See below the modified example from the help page of survSplit. The original works, as expected. If, however, a Surv object is added to the data.frame, each record gets doubled. Is there some solution other than avoiding Surv objects in data.frames? Thanks, Heinz

Hi Here is another patch regarding time in ogg123 which is more controvercial than the other one I send some days ago. (see attachment) When working with Daisy/SMIL [1] files it would be helpfull if the user could stop play at a specific time. Currently .ogg files are not allowed in the Daisy format but that will hopefully happen one day if I work hard at it. A clip in a Daisy file could look
