Apologies to the listing, the problem was with the data set and not the
code
Thanks

Before I receive a barrage of 'try looking in the help file' messages,
I
have and to no avail. For a new user of R I would like to point out
that
in order to be able to use the help files/manuals effectively one must
know the correct question and that only comes with using R!
Could someone please direct me to why I keep getting the following
error message
"Error: subscript out of bounds"
when the following code is run
z.score<-function (group) {
for (t in levels(group$Country)) { # this will
give
t countries
y<-subset(group,factor(Country)==t) #particular
analyte over all countries equal to y
#calculate overall huber mean and sigma for a
particular analyte over all countries
ov.mu<-hubers(group$X)$mu
ov.sigma<-hubers(group$X)$s
#define arrays
#p.mu<-array()
#p.sigma<-array()
#z.value<-array()
#calculate huber mean and sigma for given
analyte (defined by group) by selected country (y)
p.mu<-hubers(y$X)$mu
#p.sigma<-hubers(y$X)$s
#calculate z score for particular
analyte:country combination
#z.value<-as.vector((p.mu[t]-ov.mu)/ov.sigma)
}
#data<-list(mean=ov.mu,sd=ov.sigma)
return(p.mu)
}
# group entered as group=subset(sub2, factor(Analyte)=="Cholesterol")
for example
#
#
#
#
#
Please ignore the commented out lines, these were put in for my own
use. The code gave the same error message with them removed.
Thankyou for your help
