I am using if else and loop to sortout the data set that is the values less than o or more than 100 will be chosen.I could not get outTable with loop. Please help me to correct the code: I USED: # Read a_data <- read.table("D:/SNP/copy.sas", header=T, sep="\t") tr <- a_data$truck ca <- a_data$cars length <- nrow(a_data) outTable <- matrix(nrow=length,ncol=3)

Hi, I have encounter a problem that my data a_data.frame is of data.frame class with columns: sequenceID, eventID, items. when I convert it to transaction class: as(a_data.frame, "transactions") All columns are grouped together under items, which is like this: {sequenceID, eventID, items} instead of the right form: sequenceID, eventID, {items} Also when i read_baskets, there is

Dear all, I may have overlooked something but the following piece of code causes me trouble: > a_data.frame(1:4) > a X1.4 1 1 2 2 3 3 4 4 > apply(a,2,cat) 1 2 3 4Error in ans[[1]] : subscript out of bounds > apply(a,1,cat) 1234NULL Is this the fact my data.frame has only one dimension ? (and do I forget somewhere (but where ?) to specify not to 'drop'

Hello! I am trying to figure out how to implement *logical deletes* instead of physical deletes using ActiveRecord. Basically, in many applications that deal with E-Commerce, you really can''t physically delete almost anything, because records must be kept for auditing and customer service tracking purposes. In the past, I''ve implemented logical deletes as follows: 1.

Dear list: since it took me a little while to figure out how to make use of naresid, I thought that the below R code might be useful as an example on the help page. Regards, Markus # generate some data x1 <- runif(20) y <- 10 + 5*x1 + rnorm(20) summary(lm.0 <- lm(y ~ x1)) # append some NA's to y y <- c(y, rep(NA, 5)) # generate some further x1s x1 <- c(x1, runif(5)) #

x <- NA na.act <- na.action(na.exclude(x)) y <- rep(0,0) naresid(na.act,y) ... currently produces the result... numeric(0) ... whereas the documentation might lead you to expect NA The behaviour is caused by the line if (length(x) == 0L) return(x) in `stats:::naresid.exclude'. Removing this line results in the behaviour I'd expected in the above example (and in a

An issue came up with the rms package today that makepredictcall would solve, and I was going to suggest it to the author. But looking in the help documents I couldn't find any reference to it. There is a manual page, but it does not give much aid in creating code for a new transformation function. Did I miss something? If not, I'd be willing to draft a paragraph about that which

hi: sorry to bother you all again. I am running a simple lm(y~x+z) regression, in which some of the observations are missing. Unfortunately, the residuals vector from the lm object omits all the missing values, which means that I cannot simply do residual diagnostics (e.g., plot(y,x)). Would it not make more sense to have the residuals propagate the missing values, so that the residuals

Dear all, I'm writing a package and I would like to reuse the residuals() function. When I use a function which calls the redefined residuals (for my custom class) I get an error (see below). It looks like the wrong method is used. The strange this is, that when it execute the code manually it get no error. Any suggestions? Best regards, Thierry The entire source code is at

Hi, Does anyone know an easy way of retaining rows in a model.matrix where missing values are present in the predictors. Ideally I'd be able to retain these rows as zeros. Thanks, Jarrod -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

That site, and that document in particular, had nothing to add on this particular topic. So on to question 2. I think the material is useful. If I write it up will that be welcome/tolerated/ignored addition to the R docs?

Dear All, I have two vectors: tt = c(6.87, 7.43, 6.4, 4.5, 5.5, 5.87, NA, NA, NA, 7.7) year = 1966:1975 Residuals lm(tt~year)$res do not contain NAs for the three years of missing temperature tt. Is there a simple way to get these NAs back into the residual's vector? Thank you, Sorama [[alternative HTML version deleted]]

Hola! I have some problems with gam in mgcv. Firts a detail: it would be nice igf gam would accept an na.action argument, but that not the main point. I want to have a smooth term for time over a year, the same pattern repeating in succesive years. It would be natural then to impose the condition s(0)=s(12). Is this possible within mgcv? I tried to obtain this with trigonometric terms, aca:

The patch below attempts to correct some unclear sentences in the R documentation. In the case of coplot.Rd it wasn't clear whether "shingle" bar had a special meaning or was a typo for "single". I've just put a comment in that case. regards -- Brian Gough Network Theory Ltd -- Publishing Free Software Manuals 15 Royal Park Bristol BS8 3AL United Kingdom Tel: +44

I've rolled up R-2.12.2.tar.gz a short while ago. This is an update release, which fixes a number of mostly minor issues, and one major issue in which complex arithmetic was being messed up on some compiler platform. You can get it from http://cran.r-project.org/src/base/R-2/R-2.12.2.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will
