readNWISSample Error

[raruggie]

I am getting the following error when using EGRET::readNWISSample:

>   siteNumber <-  "04220045"
>   ParameterCd <- '00665'
>   StartDate <- "2010-06-17"
>   EndDate <- "2019-11-28"
>   Sample <- readNWISSample(siteNumber, ParameterCd, StartDate, EndDate)

Error in `[.data.frame`(data, , c("agency_cd", "site_no")) :                                                               
  undefined columns selected
In addition: Warning messages:
1: NWIS qw web services are being retired.

for more information.

2: In readLines(f) :
  incomplete final line found on 'C:\Users\ryrug\AppData\Local\Temp\RtmpW0AVhG\file3228785379f0'

In the source code for EGRET::readNWISSample I see it uses dataRetrieval::readNWISqw which has been retired and is replaced by dataRetrieval::readWQPqw. Is there an updated version of the EGRET::readNWISSample function that uses the updated WQP function?

I am using EGRET 3.0.9 and R 4.3.3.

Thank you for any help with this.

If you update EGRET to the version on CRAN (3.0.10):
https://cran.r-project.org/web/packages/EGRET/index.html
That function was updated. It should work the same, but it now calls WQP instead of the decommissioned NWIS service.
