Bayesian mixing model
...m using the BCE {BCE} function to run a Bayesian sediment mixing model. The aim is to find the optimum % contribution from each of the 4 source areas that can yield the target geochemistry. I have geochemistry for 4 source areas called Rat: Rat<-read.table(text="CaO MgO Na2O Al2O3 Topsoils 2.511250 0.7445500 0.7085500 14.10375 ChannelBanks 55.021500 0.8665000 0.3045000 10.19800 FieldDrains 17.958221 0.9415394 0.2979383 14.68013 RoadRunoff 9.177297 1.9034304 0.4618634 22.22206", header=TRUE) ...and geochemistry for 1 target sediment called Dat: Dat<-read.ta...

subset function
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

setting a number of values to NA over a data.frame.
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,

rbind-ing with empty data frame produces error
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
