Dear r-user,
I've wrote a small function to visualize the creation of a histogram.
Therefore I create a vector with random values and let them plot in
histograms. I better give a small example in R-Code:
i=0
funVec=rnorm(1000)
temp=hist(funVec,plot=FALSE)
plot(1,xlim=c(max(temp$breaks),min(temp$breaks)),
ylim=c(0,max(temp$counts)+0.1*max(temp$counts)),col="white")
for(i in 1:1000)
{
hist(funVec[1:i],add=TRUE,col="white")
Sys.sleep(1/25)
}
I don't find any mistake in the example above and nevertheless there
something strange about the result. R should plot 1000 histograms with time
breaks of 1/25 seconds between the single plots. But the program visualize
not even 100 steps. I don't understand that circumstance. If I don't use the
add parameter, R visualize all 1000 steps.
I hope somebody could help me or explain me what ist happening there. I m
looking forward to any hints or clues.
Greetings and thanks in advance
Etienne
