plotting box plots on same x
I am trying to construct a graph of 6 box plots of blood pressures. I want them to be on a single set of axis and I want the SBP to be ontop of the DBP. I have an array bp with the data in it and I tried a[1,]<-c(145,60,147,62,140,57) a[2,]<-c(160,75,160,74,160,70) a[3,]<-c(140,55,140,65,142,55) boxplot(data.frame(a), main = "Blood Pressures", at=c(1,1,2,2,3,3),

inner join sqldf
Hi, I have two dataframes that have some common columns. I would like to join them by the common columns prochi and prescribed_date as there are duplicate prochis but they will be made unique by date.

I have a couple of 64-Bit Xeon's with CentOS 4.2 x86_64 installed on them. They don't all have the same motherboards.

When I plugged the drives back in, initially, it went into a panic-reboot loop. After doing some digging, I deleted the file /etc/zfs/zpool.cache. When I try to import the pool using the zpool
