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 tried doing an inner join
but that just duplicated the columns whereas I would like the information
from the test_sql_tsf to fill the NAs in the test_sql_psd common columns.

Thanks for help,
i knew that way that you have suggested but in fact my case is a little bit complicated than this,

I am trying to allow certain nodes to override variables in inherited

Subset using partial values
Hi everyone,
I would like to subset a data.frame using partial values.
For example I have the following data.frame:
PROCHI Main_condition
1234 411
1235 4110
1236 4111
1237 I20
1238 I201
1239 I202
Now let's say that I use the Subset function. Ordinarily I would use it as
follows Subset(x, Main_condition=="411"|Main_condition=="4110" etc to get

CentOS 4.2 x86_64

Cross compiling an empty program results in a segfault
Hello,
I'm trying to cross compile an empty program on macOS for Linux:
cat test.c
int main() {
int a = 2+3;
return 0;
}
clang -o -c -target x86_64-linux-gnu test.c
If I copy the resulting test.o to the Linux machine and run clang test.o,
it works fine.
However if I try to link it on macOS, I get a segfault when I launch ./a.out

Unbootable system recovery
I have just recently (physically) moved a system with 16 hard drives (for the array) and 1 OS drive; and in doing so, I needed to pull out the 16 drives so that it would be light enough for me to lift.
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.
