Counting non-empty levels of a factor
...r several weeks of observation)
I used to do this calculation using SAS with:
proc freq data = MyData noprint ; by store ;
tables brand / out = result ;
run ;
(the cool thing was I got a database I can merge with MyData)
any idea for doing that in R ?
Thanks in advance,

Hello
I have a dataset of people spending time in places. But most people don't

length of a density curve (or any curve)
Hello R users,
When I type
d <- density(MyData$x)
I obtain a density object I can plot,

density curve ?
( I imagine I could compute the distances between the 512 equally
spaced points using their x and y, but does it exist a smarter way ?)

how to import map data (maptools?) from a html set of 'coords'
Dear R users,
I would like to draw map and import it in maptools/spatstat packages.
The 'raw data' I have come from a web page (<map>...</map>) and are
basically a list of coordinates of a polygon.
I would like to know how to import them in R; I checked the maptools
packages, but all the examples use existing .dbf files.
I just have a (serie of) text file(s) looking like
