Histograms: Boxes and lines
Could be ...
legend("topright",legend=c("Histogram","Kernel Density
Estimate"),lty=c(NA,1), lwd=c(NA,2), pch = c(15, NA), col =
c("lightblue", "black"), merge=TRUE,inset=.01,cex=.8,adj=0)

Hi folks! I'm trying to get a histogram legend to give me a filled box and
a line. The problem is I keep getting both filled boxes and a line. How
can I get rid of the second box from the code below?
x<-rnorm(1000,mean=0,sd=1)
hist(x, breaks = 50, main="Histogram of x",freq=FALSE,
xlab=" x", ylab="Density",col="lightblue", border="black")
x_dens<-density(x,kernel="gaussian")
points(x_dens,type="l",lwd=3)
legend("topright",legend=c("Histogram","Kernel Density
Estimate"),lty=c(-1,1),lwd=c(-1,2),fill=c("lightblue"),merge=TRUE,inset=.01,cex=.8,adj=0)
Thx! John
