how to keep all zeros in 1st row (not NA)
Hi, let me correct my previous post ("zeros in double matrix rather than
character matrix").
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.
In the previous post I mentioned that R makes the

Hi, how are you?
My name is Irucka Embry and I would like assistance on properly
subsetting some data obtained from a .csv file.

INFO is 92 observations of 14 variables

When the site.no is used I should have 1 observation of 14

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.
? Month
1???? 1
2???? 2
3???? 3
?temper[[1]][2]
#? Data1
#1?? 1.5

subsetting with greater than and less than indexing
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.
