error in for loop in function (object not found)
Hi all, I have attached the function file (revisedfunction) and the list
of station IDs (StationIDs) in .pdf format.
I have written a function to perform various operations on the station
IDs in two groups. The first 6 station IDs require one less step than
the remaining 68 station IDs. The file referenced at the beginning of
the function is the file containing the StationIDs.

zeros in double matrix rather than character matrix
Hi, how are you?
I have 1000 total columns with 100 rows and I have shown 4 columns of 100
rows below. I want the zeros to be read in as numerical or integer values
rather than a character. Right now I have a 100x0 character matrix rather
than a 100x1000 double matrix.
What do I need to do to read in a .csv spreadsheet with counting the zeros
as a numerical or integer value?
Thank-you.

multiple plots and looping assistance requested (revised codes)
Hi Irucka,
I tried it and was able to plot it without any errors.? Here, your code indicates you need two lines. temper[[i]][1]
?temper[[1]][1] # which is the column 1.

1???? 1
2???? 2
3???? 3
?temper[[1]][2]
#? Data1

how to keep all zeros in 1st row (not NA)
Hi, let me correct my previous post ("zeros in double matrix rather than

I have included entries from the .csv file that has 4 columns of 1000
columns and 101 rows. The first column with the "Time (day)" will not be
removed, but the row headers are the numbers 1 to 1000 and they will remain
in the matrix.

Hi Arun, thank-you for your assistance.
I'm sorry that I did not provide a reproducible example. I will provide
a reproducible example the next time.
Using the next to last line of your code I was able to get what I needed
without using the for loop.
Thanks again.

Hi, I could not open the file.
Can you load the data into R and then use the dput function?
The first link deals with dput. The latter 2 links are for dealing with
NAs in data.
