change legend character size in image.plot
I'm using the image.plot() function (fields package), but I want to enlarge
the characters of the legend (as they are too small to be read in a combined
figure), but there is no way I can find a command to do this. I can enlarge
the legend bar (with legend.witdh), axis character size (cex.axis) or the
total legend size (legend.shrink), but not the character size of the legend

[PATCH] xen/build: Remove hacked up version of figlet
This hacked up version of figlet contributes a supprisingly large proportion
of the Coverity issues found under xen/ (and therefore attributed against Xen)
Figlet can be found in all distros, so make use of it.
We keep xen.flf (being the Xen figlet font) and replace the hacked up octal
transform with a short python script.
The Xen Makefile has been tweaked in such a way that it still prints the

Greetings,
I've been doing a little testing with the stdio forwarding support added
in recent snapshots and have encountered one possible issue. First, I
should say that this feature generally seems to work. However, I haven't
been able to get it to work when connecting to a server running

How to pick colums from a ragged array?
I have a large dataset (~1 million rows) of three variables: ID (patient's name), DATE (of appointment) and DIAGNOSIS (given on that date).
Patients may have been assigned more than one diagnosis at any one appointment - leading to two rows, same ID and DATE but different DIAGNOSIS.
The diagnoses may change between appointments.
I want to subset the data in two ways:
