Hello all
I haven't got the npmc package to work yet, despite several attempts.
I'm
new to R, so this might be a stupid question, but it's taking me hours
already, so I'm asking for help.
To be exact, this is what I typed, and what R told me:
++++++++++++++++++> colsmall<-read.table("DBtest2")
> library(npmc)
> npmc(colsmall)
Error in as.vector(x, mode) : invalid 'mode' of
argument> small.data<-data.frame(class=colsmall$V1,var=colsmall$V2)
> small.data
class var
1 alpha 111.5
2 alpha 114.4
3 alpha 124.8
4 alpha 110.0
5 alpha 102.0
6 alpha 121.0
[etc]> npmc(small.data)
Error in uniroot(f = function(arg) p - z.dist(arg, corr = corr, df = df, :
f() values at end points not of opposite sign
++++++++++++++++++
The data file can be sent upon request.
What did I do wrong?
