Hi Arun, thank-you very much! The 2nd option worked perfectly. That was
what I wanted.

Now, I have another question. I am using the R packages dataRetrieval
and EGRET from https://github.com/USGS-CIDA/WRTDS. 

I have 2 objects Daily and Sample that have the naming convention (Names
= "21NC02WQ.C1000000" or whatevver the list of site names happens to be)
that I need to have after running modelEstimation, but the names are
stripped after running modelEstimation (see below). The new names after
running modelEstimation for both Sample and Daily are the names of the
columns rather than the site name.


## modelEstimation -- this is the code that I use to do the loop through
modelEstimation
for(i in Daily) {
modelEstimation(localDaily = Daily[[i]], localSample = Sample[[i]],
localINFO = INFO[[i]], windowY=10, windowQ=2,
windowS=0.5,minNumObs=10,minNumUncen=6, env=parent.frame())
}

# shows the correct naming convention before being ran through
modelEstimation
> dput(Daily)
structure(list(`21NC02WQ.C1000000` = structure(list(Date =
structure(c(11231, 
11232, 11233, 11234, 11235, 11236), class = "Date"), Q =
c(0.886534950681092,

"Day", "DecYear", "MonthSeq", "i", "LogQ"), row.names = c(NA, 
-6L), class = "data.frame")), .Names = "21NC02WQ.C1000000")

# shows the correct naming convention before being ran through

structure(list(`21NC02WQ.C1000000` = structure(list(Date =
structure(numeric(0), class = "Date"),

# shows the Daily incorrect naming convention after being ran through

)))), .Names = c("Date", "Q", "Julian", "Month", "Day", "DecYear", 
"MonthSeq", "i", "LogQ", "Q7", "Q30", "yHat", "SE", "ConcDay", 
"FluxDay", "FNConc", "FNFlux"), row.names = c(NA, -1461L), class =
"data.frame")


# shows the Sample incorrect naming convention after being ran through
modelEstimation
, .Names = c("Date", "ConcLow", 
"ConcHigh", "Uncen", "ConcAve", "Julian", "Month", "Day", "DecYear", 
"MonthSeq", "SinDY", "CosDY", "Q", "LogQ", "yHat", "SE", "ConcHat"
), row.names = 176:198, class = "data.frame")


Is there anyway to make the Name of the object Daily and Sample the site
name after being processed through modelEstimation, i.e. making the
current names the column names which they should be?

I also have a question about the INFO object that I will address in the
next e-mail.

Thank you for all of your continued great assistance Arun!
