ragged data.frame? using plyr
...(4,100),rep(5,100)))
I want to "normalise" it using the following function (unless you have
a better idea...):
adj.values<-function(dframe){
value_mean<-mean(dframe$value)
value_sd<-sd(dframe$value)
norm_value<-(dframe$value-value_mean)/value_sd
score_scale<-100
score_offset<-1000
scaled_value<-norm_value*score_scale+score_offset
names(scaled_value)<-dframe$id
return(scaled_value)
}
score_out<-ddply(dat,.(day),adj.values)
Gives me my data.frame all nice and pretty and ready to do the following:
score_out.melt<-melt(score_out,id='day')
na...
