plot POSIXct format data
...ot;1995-06-30 13:00:00"
[7] "1995-06-30 19:00:00" "1995-07-01 01:00:00" "1995-07-01 07:00:00"
.......
But it seems plot(x,y) doesn't work, y have to be numeric format. Is
there any special command for that or I should change the format of the
data?
Thanks

problem of subscript value from vector and list
...> lat[y]
[1] -10.00 -10.05
> lat[c(1,3)]
[1] -10.0 -10.1
I have no idea why it returns the wrong value when I subscripts by x,
while it works perfectly fine when I subscripts with the value of x
directly. Is there any special rule of subscripts? My version of R is
2.5.1.
Thanks a lot

Retrieve results from chisq.test programmatically
Hello,
I would like to run a series of chisq.test() and store results (x-square,
df, p-value) in a matrix for further analysis, but don't know how to do
such. Currently I run the command line for each set of data at a time and
it is time consuming.
Thank you for your help.
