I want to plot the unstadardized version of a normal plot.  Can you explain why that is not working? Dev.set(1) xcrit=-1.645 cord.x <- c(-3,seq(-3,xcrit,0.01),xcrit) cord.y <- c(0,dnorm(seq(-3,xcrit,0.01)),0)            # what does final 0 do here? curve(dnorm(x,0,1),xlim=c(-3,3),main='Normal PDF') polygon(cord.x,cord.y,col='orange') savePlot(filename="c:\\ssl_z.emf&q...

...rejection region in the form of a long rectangle to a density plot I have drawn.? I am getting? 2 plots.? How can I add rectangle to first plot?? see code below. First section works fine.? It just is not quite what I want. # NORMAL DISTRIBUTION PLOT OF RAW DATA WITH UPPER CRITICAL LEVEL - ok xcrit=144.1 # *** single-sample Upper one-tailed hypothesis Test, z statistic *** cord.x <- c(xcrit,seq(xcrit,200,0.01),200) cord.y <- c(0,dnorm(seq(xcrit,200,0.01),140,15),0) curve(dnorm(x,140,15),xlim=c(80,200),main='Normal PDF',ylab="Probability") polygon(cord.x,cord.y,col...

Hi, a questionaire data-set with more than one row for one Person make me problems. (1) i want create a function which count the used row for the relevant id ! example: id c.row 1 1 1 2 1 3 2 1 2 2 4 1 4 2 4 3 4 4 4 5 (2) i have got a problem to filter & analyse , because the filter criteria is unlucky a row above or under the ratings which i would like to
