No. The code you've written here doesn't require loading any other R libraries. Please copy and paste the exact code you've entered along with the *exact* error you are getting. Also, what is the result of sessionInfo()? -steve > > On Tue, May 24, 2011 at 9:22 AM, Steve Lianoglou > <mailinglist.honey...@gmail.com> wrote: >> >> Hi, >> >> On Mon, May 23, 2011 at 11:41 PM, Rekha <chithralekh...@gmail.com> wrote: >> > Hello All,* >> > >> > *I want to draw a histogram with density curve. * >> > >> > *For that simply i created a data called*"x" *and i used the function >> > called >> > * hist(x, col = "blue", freq = FALSE),** *from this function i got >> > a >> > histogram*. >> > >> > *After that , i tried this function* ** lines(density(x), col = "red", >> > lwd >> > = 2 ) *but i could not get the density curve. >> > >> > So, Again i used other function* curve(dnorm, col = 2, add = TRUE)** >> > *instead of the previous function for density curve. >> > >> > but still am getting error in R like this: >> > >> > Error in plot.xy(xy.coords(x, y), type = type, ...) >> > plot.new has not been called yet" >> > >> > >> > * I have used below codes to have a data and histogram with density >> > curve" >> > >> > x <- rnorm(200) >> > hist(x, col = "blue", freq = FALSE) >> > lines(density(x), col = "red", lwd = 2) >> >> You should use the code above. >> >> I don't get it though -- this is working fine for me.
