For example if I do EURODOLLAR$ED1.Comdty Date I obtain the following error: Error: inesperado símbolo en "EURODOLLAR$ED1.Comdty Date" I have also tried using . or _ instead of the space and have obtained no succes. How do I

Hello R-Users, I have the following problem with the subset function: See the following simple linear model. Here everything works fine: >germany<-lm(RENT~AGE1, in.mi01) However, if a use the same regression equation and only specify a subset, I get an error message: > berlin<-lm(RENT~AGE1, in.mi01, subset=C_X01=="Berlin") Error in lm.fit(x, y, offset

This is probably a simple problem but I don't see a solution. I have a data.frame with a number of columns where I would like 0 <- NA thus I have df1[,144:157] <- NA if df1[, 144: 157] ==0 and df1[, 190:198] <- NA if df1[, 190:198] ==0 but I cannot figure out a way do this. cata <- c( 1,1,6,1,1,NA) catb <- c( 1,2,3,4,5,6) doga <- c(3,5,3,6,4, 0) dogb <- c(2,4,6,8,10,

Hi all, I'm having some trouble with rbind - this may be a bug or it may be my misunderstanding. If I do fileName <- paste(tempdir(),"test.txt",sep="/") file.create(fileName) x <- read.table(fileName, col.names=c("one","two","three")) I get a data frame with no rows, as documented. If I then try to rbind this with another data frame

Dear all I am trying nlme together with Pinheiro/Bates book. I constructed grouped data object with suitable plotting layout (according to some common factor, panels from bottom to top are in increasing order). When I do nlme(... some stuff...) I get fitted object which I can plot with plot(augPred(fit.nlme6, level=0:1)) but it results in completely different ordering. Is there any way

Hi there, I recently posted about problems with winbind resolving names from ADS. We have an ADS Domain Controller serving the domain MED-DUS and an NT 4 PDC serving the domain MEDOIL. We want to use a samba server as memberserver in the MED-DUS domain. I joined the samba server to the MED-DUS domain. The domain join worked ok. All users (including MEDOIL) are visible. Next i started winbind.

Hello R-users, I would like to use subscript in chemical formulas for the different treatments in a boxplot. Fot title, xlab and ylab sub- and superscript is no problem, but for the different treatments of the following example I cannot get subscript. Example: weight <- c(6,5,7,2,7,3,9,4,2,7,8,9,2,3,4,5) treatments <- as.factor(rep(c('Control',

Hi, Op 3-okt-06, om 20:48 heeft Chris Lattner het volgende geschreven: > You'd have to change it to something like: > > void foo(int X, ...) { > P = va_start(); > bar(X, P); > } > > void bar(int X, valist P) { > use(P); > } Can the other va_...-intrinsics be used in bar as were the "P = va_start" in bar? The va_start probably is unnecessary

Dear R users I use R (1.3.0) Windows version usually with connection to Excel sheets via RODBC Version: 0.8-2. Everything is OK until I use mixed data types (numeric and character) in one column. In that case I will get a particular column of data frame with NA's. Example vzorek lpas apas NA 51.240 20.26 NA 51.340 20.42 NA 49.770 22.05 RB 12 49.840 19.30 RB 12 49.880

There is an implicit dependency between vastart and the function it lives in. Specifically, if you have:
