Dear friends,
After i calculated the k-function, i wanted to get the plot of the
distance and k-function, but an error occured that i didn't met before. The
following is my programs and the version information.
ppa<-read.csv('d:/deleting/ppa.csv',sep=',',header=T) # a point dataset
ppa<-as.points(ppa)
s<-seq(0,40,1)
khatv<-khat(ppa,bboxx(bbox(ppa)),s) #calculate functions
plot(s, sqrt(khatv/pi)-s, type='l',lty=1,lwd=1, ylim=c(-2,2)) # the plot
can't generated automatically, but no error occurs. It seemed to be
right, because i used it in version 2.3.1.
But, if you do,
nptg<-528
nsim<-99
kenvcsr<-Kenv.csr(nptg,bboxx(bbox(ppa)),nsim,s)
lines(s, sqrt(kenvcsr$upper/pi)-s, lty=2, lwd=2) #??????ERROR OCCURS
Error is plot.xy(xy.coords(x, y), type = type, ...) :
plot.new didn't be transfered
