...a pivot table in excel or by using SQL queires. I have a moderately sized data set of ~70,000 records and I am trying to compute some group averages and sum values within groups. the code example below shows how I am trying to go about doing this pti <-rnorm(70000,10) fid <- rnorm(70000,100) finc <- rnorm(70000,1000) ### compute the sums of pti within fid groups sum_pinc <-aggregate(cbind(fid,pti),list(fid),FUN=sum) #### compute mean finc within fid groups tot_finc <- aggregate(cbind(fid,finc),list(fid),FUN=mean) when I try to do it this way I get an error message telling me th...

Dear Listers, I am drawing a plot of two density curves, for male and female incomes. I would like to shade/hatch/color (whatever) the areas under the curves which are distinctive for each gender. This is the code I have tried so far: m <- density(topmal.d$y, bw = "sj") f <- density(topfem.d$y, bw = "sj") par(mfrow = c(1,1)) plot(x = c(0,400), y = c(0,0.02), type =

Hi Keir, this patch changes common code of xen hypervisor, but seems we have to, because current call to do_boot_vcpu is always from domains, however, for SMP VMX guest AP bring up, we need call it from xen hypervisor, so we''d like to split it.
