Hi Sorry for banal question How to create empty data frame with for example 30 variables without typying: data.frame(x=1,y=1....) Jarek

Dear All! I'm looking for equivalent of Matematica function "Which" which works as follows: z = Which[x<10,0.3, 10<=x<20,0.5, 20<=x<100,1] where x is a vector I can replace it with custom function with set of ifelse but I'm looking for simpler and faster (much faster) solution best wishes Jarek

Hi I'm looking for solution or function which I can use to sample data frame, to obtain new (smaller) data frame similar to sample() function Jarek Jasiewicz

Hi I have the problem with fitting curve to data with lm and glm. When I use polynominal dependiency, fitted values from model are OK, but I cannot recive proper values when I use coefficents to caltulate this. Let me present simple example: I have simple data.frame: (dd) a: 1 2 3 4 5 6 b: 3 5 6 7 9 10 I try to fit it to model: model=glm(b~poly(a,3),data=dd) I have following data

Hi It is probably simple but how to force in plot command number format: 20000, 30000, 40000 etc. instead of 2e+04, 3e+04 etc. example of command: plot(x=data$along, y=data$rzedna,type="l", xlim=c(0,max(data$along)), ylim=c(200,1200), main="", xlab="length", ylab="height", cex.main=2, cex.lab=1.5, cex.axis=1.2, lwd=2) thanks Jarek

I've been trough the R documentation for about half an hour and it's not clear to me how to do this: I need to format to character a series of integers from 1 to 1000, and I like them to look like "0001" "0002", "0059", "0123" and so on. Padded with zeroes to have four digits. Cheers! Mario. r-help-request at r-project.org wrote: > Send

Hello, Is it possible to trigger an action in a controller when a table from database changes? I thought about using an utility like cron (railscron) to check every, e.g. 2 s, if the table changed, but I am wondering if there is a solution a bit more ''elegant'': to trigger an action exactly when the change is made. Best regards, -- Kuba Nowak

Hi all, I'm trying to use an iteration that appends something to vector 'peaklabels' like so: peaklabelNames <- append( peaklabelNames, substitute(i^{z+phantom()}*" ("*a*"AMU)",list(i="y2",z=2,a=0)) ) The vector is supposed to be used with 'text' to put labels on signals in an impulse plot. While not vectorized

Why is class(spectrum[["Ion"]]) after this "factor"? spectrum <- cbind(spectrum,Ion=rep("", nrow(spectrum)),Deviation.AMU=rep(0.0, nrow(spectrum))) slowly going crazy ... Joh

Hi all, I asked something like this earlier but decided that a proper minimal example might be helpfull ;0) Why does this work with regards to the expression (substitution): require(stats) plot(cars) text(5,120,labels=substitute(i^{z+phantom()}*"("*a*" AMU)",list(i="yx",z=2,a=0))) text(c(5,5),c(115,110),labels=c("One","Two")) But adding this

I have a current RELENG_7 running on: http://www.supermicro.com/products/system/4U/7045/SYS-7045B-TR+.cfm with the -3+ IPMI card.
