[.data.frame speedup
Below is a version of [.data.frame that is faster for subscripting rows of large data frames; it avoids calling duplicated(rows) if there is no need to check for duplicate row names, when: i is logical attr(x, "dup.row.names") is not NULL (S+ compatibility) i is numeric and negative i is strictly increasing "[.data.frame" <- function (x, i, j,

data frame subscription operator
Hi all, I was looking at the data frame subscription operator (attached in the end of this e-mail) and got puzzled by the following line: class(x) <- attr(x, "row.names") <- NULL This appears to set the class and row.names attributes of the incoming data frame to NULL. So far I was not able to figure out why this is necessary - could anyone help ? The reason I am

Documentation of S3 and S4 classes, inheritance
I'd like to have a class A that computes a likelihood, and a subclass B that computes the same likelihood by sometimes throws in an additional term (B includes measurement error). So B's likelihood needs to call A's, and then (sometimes) multiply by an additional term. It sounds as if, in the S3 scheme, NextMethod is supposed to do this: like.A <- function(stuff) compute value

SV: Documentation of S3 and S4 classes, inheritance
I am sure that I do not have the answer to your question - but I would like to add to your views regarding the S4-issue. I've been involved in the gRbase package for graphical modelling in R. The first version was implemented in S4 but now we have made a roll-back to using S3 methods. While, I can see that S3 is not really comprehensive enough for 'proper' object oriented

Hmisc latex() does not want to work
I seem to have a problem getting latex (Hmisc) to work. Any suggestions as to what I am doing wrong?

Genotype importing from Sequenom
Sequenom has an odd format of calling a SNP genotype gg [1] "C" "GA" "A" "C" "C" "AG" "C" "C" "T" "G" homozygous A is called A and heterozygous is called AT The genetics package cannot handle the fact that some genotypes are declared with 2 letter while other are declared with only 1.

Unusual System State
I have seen *some* similar activity in different machines through the years and it *always* turns out to be a hardware issue. If this machine is particularly old, I would be suspicious of that.

using mapply to avoid loops
Hello, I would like to use mapply to avoid using a loop but for some reason, I can't seem to get it to work. I've included copies of my code below. The first set of code uses a loop (and it works fine), and the second set of code attempts to use mapply but I get a "subscript out of bounds" error. Any guidance would be greatly appreciated. Xj, Yj, and Wj are also lists, and s2,

Prefered Method for UPS?
Hello, since I had delayed the programming of the UPS Device part, now it is time to continue... My Device is "24 V DC modular ATX PSU" which replace the standard ATX Power Supply in PCs and use 15-43 V Input Voltage. The microcontroller is a TI LM3S5T36 Cortex M3 and I get the "UPS" infos using up to 4 Maxim DS1780 and some I?C current sensors. The ATX PSU has 4

Same output in NUT as from APC tools?
Hello, Since I have now nearly all stuff running on my LH7A404 and now I am working on my DS80C411, I like to know, whether NUT show the APC UPS stats like the APC tools. Currently I do not know, HOW NUT triber the USB-Poert to get out the infos of the UPS. In theory I do send out only arround 5-60 lines of data which then NUT or any other programs must parse or something

as.matrix.data.frame() in R 1.9.0 converts to character when it should (?) convert to numeric
Conversion of a data frame to a matrix using as.matrix() when a column of the data frame is POSIXt and all other columns are numeric has changed in R 1.9.0 from R 1.8.1. The new behavior issues a warning message and converts to a character matrix. In R 1.8.1, such an object was converted to a numeric matrix. Here is an example. #### R 1.9.0 #### > foo <- data.frame(

connect points in charts
Hi is there a automatic way that long distances between points are not connected. I have something like plot(x,y,type="o",...) atx <- seq(as.Date("2009-04-01"),as.Date("2011-04-01"),"month") axis.Date(1, at=atx,labels=format(atx, "%b\n%Y"), padj=0.5 ) but I do not want lines between points whose distance is greater than two weeks. thx
