[R] plot question
Hi everyone, I have what may appear to be a newbie question, but I have looked everywhere I can think to look and I cannot find an answer. On page 35 of An Introduction to R the following command appears: plot(ecdf(eruptions), do.points=FALSE, verticals=TRUE). What is the do.points argument? I know what it does (suppresses printing of the points) but where can I find help on it? I want to be able to explain it fully to my students.

Re: [R] plot question
Take a look at ?plot.stepfun. 'ecdf()' returns an object of class ecdf inheriting from class stepfun and 'plot.ecdf()' calls 'plot.stepfun'. -roger Catherine Carter wrote: Hi everyone, I have what may appear to be a newbie question, but I have looked everywhere I can think to look and I cannot find an answer.

If you are aware of how R uses method dispatch, then you might know that the plot() function is a generic method and that plot.ecdf() is the specific method that is called when the initial argument is of class ecdf, as is the case above. Thus, using ?plot.ecdf will get you to the help page, where there is a notation in the Arguments section that the '...' arguments are then passed to plot.stepfun(). 'do.points' is passed in this fashion, so using ?plot.stepfun will then get you to the help page where 'do.points' is defined as: logical; if true, also draw points at the (xlim restricted) knot locations. 2. Using: RSiteSearch(do.points, restrict = functions) will search the online function documentation, bringing up a browser window, where the first link gets you to ?plot.stepfun.

Re: [R] plot question when type = b and pch is a vector
Dear tokas,
How about:
x - seq(0.01, 10, length = 20)
xx - x[7]
x[7] - NA
plot(c(0, 10), c(-20, 20), type = n, xlab = x,
ylab = expression(2 * alpha * log(x)))
for(i in 1:4){
lines(x, 2 * i * log(x), lty = 1)
text(xx, 2 * i * log(xx), i)
}
I hope this helps,

Subject: [R] plot question when type = b and pch is a vector
Dear R users,
I've been struggling some days with the following
problem: I'm interesting in producing the following plot
x - seq(0.01, 10, length = 20)
plot(c(0, 10), c(-20, 20), type = n, xlab = x,
ylab = expression(2 * alpha * log(x)))
pch. - rep(NA, length(x))
for(i in 1:4){
pch.[7] - as.character(i)
lines(x, 2 * i * log(x), type = b, pch = pch., lty = 1) }
where all the line segments are connected, except from the
7th one where I've put the value of alpha -- in other words
I'd like to produce a line plot where the label appears at
each line with some white space around it.
thanks in advance,
tokas

Re: [R] plot question

I refer you to ?title and its given examples.
try this --
plot(rnorm(10),rnorm(10),xlab= ,ylab= )
title(xlab=year,
ylab=expression(paste('M x'*10^{3},)),font=2)
note that 'title()' will alos accept a list for x and y labs,
for additional parameters,e.g., 'col' and 'cex'

Re: [R] plot question
Gabor,
I thought that I had worked around the 'expression' format problem,
but if the x-y labels are to be bold, then using,say, cex.lab=1.25in the
title(), appears to simulate 'bold' font very well, both for the ylab maths
expression and xlab text.
Your solution is the rigorous one!
John
for example --
plot(rnorm(10),rnorm(10),xlab= ,ylab= )
title(xlab=year,
ylab=expression(paste(M x*10^{3})),font.lab=1,col.lab=4,
cex.lab=1.25)
Gabor Grothendieck wrote ---
Trying characters and expressions variously it seems that font.lab applies
to character strings but not to expressions so if you want to use an
expression
just use bold (or whatever) explicitly on the expression. One gotcha is
that
bold will not work as one might have expected on numbers so they must
be represented as character strings -- which is why we have used 3 rather
than 3 below.
plot(rnorm(10),rnorm(10),xlab=quote(bold(year)),ylab=quote(bold(Mx10^3))

Re: [R] plot question
At least on Windows XP R 2.1.1 it does seem like there is quite a
difference to me, at least when done side by side, which can be
seen like this:
plot(rnorm(10),rnorm(10),xlab=,ylab=)
title(xlab=x,ylab=quote(bold(3*4)),font.lab=1,cex.lab=1.25,col.lab=blue)
since the cex.lab will act on both 3 and 4 but bold will only act on
the 4 since numbers such as 3 in the example are ignored by bold.
Maybe in isolation it would suffice.

Use 'xlim' to specify the range of the x axis:
plot(c(0.5, 1, 0.5), type = 'o', xlim = c(0, 4))
