Re: [R] Plotting a large time series

Hi Adrian, This is probably taking a long time. I first tried with 7x10^6 times and values and it took several minutes. The following code does what I expected: amdat<-data.frame(time=1:70,value=rnorm(70,-4)) amdat$value[amdat$value<0]<-0 sum(amdat$value) [1] 5.07101

Check the size of df_both. It would be that there are no Command fields that contain both a 't1' and 't2'. You can so do: sum(grepl("t1", df$Command) & grepl("t2", df$Command)) to see how many Command fields contain both. Jim Holtman Data Munger Guru What is the problem that you are trying

'grepl' returns a logical vector; you have to use this to get your subset. You can use: df_tq <- subset(df, grepl("t1", Command)) df_t2 <- subset(df, grepl("t2", Command)) # if you want to also get a subset that has both, use df_both <- subset(df, grepl("t1", Command) & grepl("t2", Command))
