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?...

Hi all, I´m trying to use write function to save the 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

Hi all, I want to make the following: I want to run a linear regression on each column of a matrix "estima" on the correspondent column on the matrix "estima2". You see I want to regress estima[,1] on estima2[,1] this way to all columns.... At the same time I want to make a regression adding each time a new observation. You see, the first regression will regress only one

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

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!
