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 Jingru Dai ---- School of Mathematical Sciences Rm 454, Building 28 Monash University, 3800 Victoria, Australia

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 Jingru Dai ---- School of Mathematical Sciences Rm 454, Building 28 Monash University, 3800 Victoria, Australia

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. --My Coyne [[alternative HTML version deleted]]
