R neophyte question.
Hi all,
I'm currently working through the "Beginner's Guide to R" (Zurr et al.) and
I'm wondering about the first exercise in chapter 3:
I imported the data from BirdFluCases.txt and executed the 'names' and 'str'
functions as follows:
Bird = read.table(file='C:\\rbook\\BirdFluCases2.txt', header=TRUE)
names(Bird)

Help with setting the y-axis in a plot.
Hi all.
I'm working on an assignment for a psychology class and I am not sure how to
adjust the y-axis so it displays the range: 0, 5, 10, 15
The code below is almost ideal:
lsd = c(3, 5, 13)
mar = c(1, 2, 3)
g_range <- range(0, lsd, mar)
plot(lsd, type="o", col="blue", ylim=g_range,
axes=FALSE, ann=FALSE)
axis(1, at=1:3,

Creating a scatterplot with sequential dates on x-axis?
Hi all.
I need to plot 30 values and I'd like the x-axis to have 30 dates values,
e.g., 5/1/2011, 5/2/2011, etc. so an observer could see how the values
correspond as the month progresses.
Is there a convenient function I could use? I considered creating two
vectors, x and y, then simply plotting those.
Thanks,
~Caitlin

Problem loading package 'JGR' using R-2.15.0 (Win32).
Hi all.
Upon attempting to load the 'JGR' package, on a Win32 machine (SP3), a
pop-up message appeared stating that R had encountered a problem and needs
to close. Has anyone else encountered this?
Thanks.

Plotting multiple vectors in one window?
Hi all.
Using the following code:
plot(bsa, abs, col='blue', pch=16, xlim=c(0, 25), ylim=c(0.0, 1.0), xlab =
expression(paste(BSA, " (", mu, "g)", sep="")), ylab=expression(A[595]))
plot(unknown1, abs2, col='blue', pch=16, xlim=c(0, 25), ylim=c(0.0, 1.0),
xlab = expression(paste(Unknown_1, " (", mu, "g)", sep="")),

Nested for loop
...ion of 400, samples 101-200 to be taken from a sample of 800 and
samples 201-300 from a population of 300. The end result should look
something like a heart rate monitor.
Aside from the rationale, does what I'm explaining make sense?
Best,
Kirsten

Constructing a histogram with words as labels as height as frequency?
Hi all.
I need to construct a plot showing words on the x-axis and how many times
each word was given as a verbal response on the y-axis as solid bar
(frequency). Is there a convenient function to do this in R? I considered
hist(), but I'm not sure how to construct the text file. Example:
apple, 2
pear, 14
house, 1
beach, 5
computer, 15
Thanks,

Unable to connect to 'cran.r-project.org' on port 80.
Hi.
I recently upgraded my R installation to 2.11.0 on Windows XP (SP3) without
changing any firewall settings. When I attempted to update my package list,
the 'Select a mirror' took much longer than it normally did, and after I
finally selected the site, I saw:
