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?
