Hi,

I'm trying the brlr function in a penalized logistic regression function. 

However, I am not sure why I am encountering errors. I hope to seek
your advice here. (output below)

Thank you! Your help is truly appreciated.

#No error here, the glm seems to work fine
> genes.cox1.glm1<-glm(as.formula(paste(paste('as.integer(sim.cv.cox.yhat1)~'),paste('sim.dat.tst[',genes.cox1.rows,',]',sep="",collapse='+'))))

#Something happened here ... I only substituted brlr for glm
 > genes.cox1.glm1<-brlr(as.formula(paste(paste('as.integer(sim.cv.cox.yhat1)~'),paste('sim.dat.tst[',genes.cox1.rows,',]',sep="",collapse='+'))))
Error in eval(expr, envir, enclos) : y values must be 0 <= y <= 1

#using the test data in brlr gives the same error if the dependent is
reduced to one column, is it a problem with my dependent? It works
fine as per the original vignette with
brlr(cbind(grahami,opalinus)~height ...)
> brlr(grahami~height+diameter,data=lizards)
Error in eval(expr, envir, enclos) : y values must be 0 <= y <= 1
 
#This is how the objects look
> as.integer(sim.cv.cox.yhat1)
