Hello, I am considering giving a talk at my university on R to (mostly) academics. There wouldn't be any statisticians, but professors from mathematics, psychology, economics, etc. who do use some statistical software in teaching and/or research, and have an acquaintance with procedures and graphics used in statistics. Has anyone given such a talk to a similar audience? If so, I would be

Hello, Suppose I simulate 20 observations from the Poisson distribution with lambda = 4. I can summarize these values using table() and then feed that to barplot() for a graph. Problem: if there are empty categories (e.g. 0) or empty categories within the range of the data (e.g. observations for 6, 7, 9), barplot() does not include the empty cells in the x-axis of the plot. Is there any way to

R users, In S, there was a function called usa() that would draw the map of the United States, plus it had other options for graphics. I have looked but I can't find the equivalent in R. Is there one? Thanks, Jason

Suppose I have a text file that I want to read into R like the following: X Y 649 699 657 891 714 632 849 727 721 597 791 868 874 652 405 978 733 549 790 This is a simple example -- I could have a huge file with many columns of unequal lengths. What is the best way to do it? I can't see how a data frame can be used. I checked the FAQ and did a web search on the topic but I came up

Hello, I need to create a scatterplot where the y-axis is upside down. If I have non-negative bivariate data in objects "x" and "y," then the operation plot(x, -y) gives me the figure I want -- a mirror image of plot(x, y) -- except that the y-values (coordinates) are negative, which I don't want. Is there a simple way to do this? Jason

Hello, With the new version 2.2.0, I get strange plots when using the histogram-like option in plot(). For example, a plot of binomial probabilities: > plot(0:10,dbinom(0:10,10,.1), type = "h", lwd = 30) gives me weird fat cirular bars, with mass out at values with low probability. What is the issue here? This never happened with earlier versions. R on Windows XP SP 2 Intel
