I am trying to create plots within a for loop and output them to a pdf. Here is a working example using plot: gg <- data.frame(datadate=1:4, spread=5:8) pdf() for (i in 1:3) { plot(gg$datadate, gg$spread, main=i) } dev.off() I am trying to learn more about ggplot2 so I try a slight modification and it doesn't work. Anyone know how to do this using qplot in ggplot2?...

...output of a program (my constructed "H" matrix) randz<-matrix(rnorm(1000000),500,2000) H<-matrix(0,500,2000) H[1,]<-randz[1,] for (j in 1:2000){ for (i in 2:500){ if(i<251) H[i,j]<-0.6*H[i-1,j]+randz[i,j] else H[i,j]<-H[i-1,j]+randz[i,j] }} write(H, file = "datad.txt",2000) If I ommit the 2000 on write function it only puts 5 columns. The problem is that if I use this it seems it is not saving the same data I have simulated....or this seems to me. You see if I type H[,1] it is not the same that includen on the firs column on datad.txt? I feel very...

I tried a date by date forecast of a time series and it seems to be too wild. How can I aggregate the date into weeks or months as required? Thanks. The input looks like ID datadate("YYYY-MM-DD") value_for_day -- ----- ------- -- ------ -------- and I want to be able to change it to ID dataweek value_for_week or ID datamonth value_ for_ month

I am running R 2.1.1 in a Windows XP environment. I wish to use the sqlSave command to export a dataframe into Microsoft SQL. My dataframe is called temp and has 2 ?columns?, ?monthenddate? and ?value?. Monthenddate is in 'POSIXct', format. (i.e. 'POSIXct', format: chr "1984-01-31" "1984-01-31" "1984-01-31" "1984-01-31" ...). How can I

Great news! yay! I downshifted to dovecot 0.99-14 and pop server is working! Finally a pop-server and postfix and all! And no Courier! or Qmail! Whatever changed in the 1.0 release regarding MySQL is broken, and is working in the .99-14 release. I can finally use my mail server! :-) I'll keep an eye out for the 1.x stable release, hopefully it will have MySQL support working. Maybe
