R devel - Dec 1999 - hist() with horiz=TRUE does not give horiz. plots (PR#372)

If you use the horiz= option with hist() you get the message:

Warning:
parameter "horiz" couldn't be set in high-level plot() function.

and the plot comes out vertical.  The documentation says this option comes from

barplot() and it does work correctly in barplot().

This message comes whether horiz= is set to FALSE or TRUE.

The warning message you are getting is just telling you that "horiz"
is not
a valid argument to hist() (and that it is not a valid par() either).
"horiz" is quite specific to barplot().

what was the documentation that lead you to try "horiz" with hist() ?

paul

p.s.  you can "fake" a horizontal histogram using barplot.  for
example, try
...

x<-rnorm(20)
par(mfrow=c(1,2), pty="s")
hist.info <- hist(x, breaks=-3:3)
barplot(hist.info$counts, space=0, horiz=T)
axis(2, labels=-3:3)

... but perhaps you would prefer it if we made it so that you could use
"horiz" with hist() ?

Paul,

Thank you for your quick reply.  The reason I thought horiz= would work with
hist() is that it does in Splus.  (I was converting an S script to R.)  In
Splus, help(hist) syntax denotes by ... "additional arguments to
barplot".
However, I just noticed that in R, help(hist) denotes by ...  "further
graphical parameters to 'title' and 'axis'".

Please consider adding this functionality to hist().  In the mean time, I'll
try out your barplot() example as a possible replacement for my hist() command.
Thank you for providing it.

P.S. Please say hello to Ross for me if you see him.  He was a housemate of
mine in graduate school.
