numerical subscripts in a loop in a plot
Hi R Graphics Gurus I am unable to figure out this issues with unevaluated expressions. I'm trying to create a graphic where I calculate the residual from a regression and want to mark each residual with its observation number. So something like plot(0,0, type = "n", xlim = c(0,10)) for(i in 1:10){ text(i, 0, substitute(paste(epsilon[i]))) } except that i end up pasting

precision issue?
Hi R Gurus, I am trying to figure out what is going on here. > a <- 68.08 > b <- a-1.55 > a-b [1] 1.55 > a-b == 1.55 [1] FALSE > round(a-b,2) == 1.55 [1] TRUE > round(a-b,15) == 1.55 [1] FALSE Why should (a - b) == 1.55 fail when in fact b has been defined to be a - 1.55? Is this a precision issue? How do i correct this? Alex

strings as factors
Hi, To be able to match cases with a benchmark I need to have a data.frame with a character id variable. however, I am surprised why this seems to be so hard. In fact I was unable to succeed. Here is what I tried: >test1 <-expand.grid(ID = 1:2, sex = c("male","female")) >is(test1[,2]) [1] "factor" "oldClass" >test2 <-expand.grid(ID =

map issues
Hi ! I have a shapefile that I can easily read into R using library(maptools). My problem stems from some warning messages that come even though everything seems to work fine. library(maptools) districts <- read.shape(filen = "a_ds", dbf.data = TRUE) length(districts$Shapes) so far so good. when I try and plot this I get a nice plot and a warning message: > plot(districts)
