Name all your arguments (the vignette gets this wrong), including
siteNumber=siteNumbers.
Also, the vignette uses 'statCd', not 'statCD'.
dataAvailable <- whatNWISdata(siteNumber=siteNumbers, service="all",
statCd="all")
gives some results.

This worked:

'data.frame': 2565 obs. of 24 variables:

$ site_no : chr "14207920" "14208000" "14208000" "14208000" ...

You failed to name the first parameter, siteNumbers?

I'm learning the dataRetrieval package. Following the example in Section
1.1.2 of the vignette (whatNWISdata) I prepared this script:
--
library("dataRetrieval")
siteNumbers <-
c("14207920","14208000","14208200","14208300","14208500","14208600","14208700","14208850","14209000","14209100","14
A is not a matrix. I presume you meant B. If so:
> B[!C] <- 0
> B
[,1] [,2] [,3] [,4]
[1,]1600
[2,]2000
[3,]3000
[4,]400 19
[5,]5000

The result that I want to get is this:
for (i in 1:5) {
for (j in 1:4) {
B[i,j] <- ifelse(C[i,j]==FALSE,0,B[i,j])
}
}
I would like to know if I can do this without loops.

Hi
I would like to get help in combining two matrices. Here is my example:
A <- 1:20
B <- matrix(A,nrow=5,ncol=4)
# B is a numerical matrix
C <- B<7
C[4,4] <- TRUE
# C is a logical matrix
# if I combine A and C, I get a vector
D1 <- A[C==TRUE]
D1
D2 <- A[C==FALSE]
D2
I want to get a matrix with th
7 matches
