when use xyplot and abline, error: plot.new has not been called yet


theta<-seq(90,110,0.01)
xyplot(F1(theta)~theta,type="l", col = rgb(red = 255, green = 90, blue = 0, maxColorValue = 255), cex.lab = 3.5, cex.axis = 3.5, lwd=2 )
abline(a=NULL, b=NULL, h=NULL, v=100)



F1 is defined as a whatever function, and I got


Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) :
plot.new has not been called yet





you are mixing base r plotting and lattice . see stackoverflow.com/questions/11949766/… for abline in lattice
