Subsequent to Roger's suggestion I will shortly be sending a link to a
site where the shapefile
in question and it's various extensions can be downloaded as a zip file.
Any and all assistance with this problem are greatly appreciated.

Under spatstat 1.15-0 and maptools 0.7-16 there is a bottleneck which causes
'as.psp.SpatialLines' to become ve
There is a function that does this well called psp() in the spatstat

As you've indicated Roger there does appear to be an error in
readShapeLines() under maptools. However I can't help but wonder why I do
not have any problems using the same command sequence for a subset of
the same data (even after updating my version of sp)...? With said subset I
am able to impo

Hi,
could you provide an example for the data in "sample"? (incidentally,
note that sample is already the name of a built-in function)
I'm guessing you could do something like,
library(doBy)
summaryBy(count~ID, data= count_myData, FUN=sum)
tested with,
count_myData <- data.frame(ID=rep
Dear R user,
Thanks for this sunday attention about my problem. I have a data.frame like
this example:
count_myData
ID: 1,1,1,1,2,2,2,3,3,3,3,3,4,4,4,4,4,4
count: 4,4,4,4,3,3,3,5,5,5,5,5,6,6,6,6,6,6
this data.frame derived from this code
count_myData <- ddply(sample, .(ID), transform, sum = su
