It looks like the text didn't show assigning the results of factanal
to an object. Try:
pgdata<-read.table("pgfull.txt",header=T)
names(pgdata)
pgd<-pgdata[,1:54]
#missing line
model <- factanal(pgd,8)
par(mfrow=c(2,2))
plot(loadings(model)[,1],loadings(model)[,2],pch=16,xlab="Factor
1",ylab="Factor 2")
plot(loadings(model)[,1],loadings(model)[,3],pch=16,xlab="Factor
1",ylab="Factor 3")
plot(loadings(model)[,1],loadings(model)[,4],pch=16,xlab="Factor
1",ylab="Factor 4")
plot(loadings(model)[,1],loadings(model)[,5],pch=16,xlab="Factor
1",ylab="Factor 5")
