fdays = factor(Days)
fvar = factor(variety)
my model is:
test1 <- gam(O_EC~s(WRM)+PWM+fdays+fvar)
Now, I can easily measure O_EC, PWM, fvar, and fdays, but not WRM.
I can get a good estimate for s(WRM) by straight algebra and get a rough eyeball estimate of WRM from the s(WRM) vs WRM plot:
s(WRM)...

Cause of Error 1:nrow(X) : argument NA / NaN
Dear R Helpers
I am trying to get function smedian.hilow to work using Hmisc summarize
on variable conc in dataframe pkindivmtd by time and dose using:
attach(pkindivmtd)
sconc <- summarize(conc,llist(time,dose),smedian.hilow)
I get the error message
Erreur dans 1:nrow(X) : argument NA / NaN
Contents of pkindivmtd is
> contents(pkindivmtd)
Data frame:pkindivmtd 1296 observations
