Hi Please cc your mails to r help. Users are around the world and you could have response oslo from others. You need to put NA in a missing good or bad letter. I would probably do merging instead of do.call but there may be other options. Something like that. > l1<-sample(letters[1:10], 5) >

Hi Cristiano, Might be the data you have for "dv". I don't seem to get the problem. dv<-sample(1:6,15,TRUE) subject<-factor(rep(paste("s",1:5,sep=""),each=3)) myfactor_c<-factor(rep(paste("f",1:3,sep=""),5)) mydata_c<-data.frame(dv,subject,myfactor_c)

Dear all, I am trying to visualize the regression coefficients of the linear model that the function aov() implicitly fits. Unfortunately the function summary.lm() throws an error I do not understand. Here is a toy example: dv <- c(1,3,4,2,2,3,2,5,6,3,4,4,3,5,6); subject <-

In hopes of isolating parts of a time series where my indicator is above zero I have filled those rows where the indicator is <= 0 with NAs. I was hoping this would leave blank gaps when I plotted using chartSeries(blanked, theme = 'white'), but chartSeries closes up the gaps. ggplot, however,

Re: [R] Error in cut.default(a, breaks = 100) : 'breaks' are not unique

It should cover the range of values - from below the minimum to above the maximum of your data. One break would do it, or 10, or whatever. It doesn't matter how many breaks you have, it matters that they have a sufficient range. So you might make breaks like seq(floor(min(x)), ceiling(max(x)),

You can add the argument na.print=" " to print() to make the missing values print as " " instead of as NA. Some, but not all print methods support this. E.g., > print(c(1,2,NA,4,5,NA), na.print="-") [1] 1 2 - 4 5 - > print(matrix(c(1,2,NA,4,5,NA),2), na.print="-") [,1] [,2] [,3] [1,]
