[R] Insert .eps files in to an R plot.
Hello Everybody, I have an eps figure an awesome bacteria and a plot (generated using R) also in eps format. Now it looks like there is space for only one figure and I have to insert the picture of the bacteria into the plot. Is there a way to insert figures (eps/png/jpg) in to plots (may be control over placement of figures in the plot as well?) ? By plots I mean data represented using axes and points and such and by figures I mean cartoons, pictures taken by a camera and such.

[R] Help with calculating entropy of data
Hello All, My question is not directly related to R but rather on which statistical method I should look in to for capturing the entropy of a data-set as a number. In this figure http://www.twitpic.com/18sob5 are two data sets blue and green (x-axis is time) that fluctuate between (-1,+1). Clearly, green has 4 jumps while blue has 1 (and a some?). Intuitively, green has more entropy than blue. Is there a robust statistical quantity that can capture their relative flexibilities? Additionally I am hoping this method will differentiate between two cases where both spend 50% of time in each of the states -1 and +1 but one has more jumps than the other. I am guessing the limits of that quantity are 0 (no change) and N-1 (for N time steps). Sigma( mod(value(t)-value(t-1))/2 )? I am just thinking out loud here. I have about 200 such plots and I would like to arrange them in order of their entropy. Thanks and I sincerely apologize if you feel this is not the right place to ask this question.

[R] Multiple figures margin problem
Hello All, I am trying to make a figure with 3x2 plots in it. Let us name the plots as such: 1 2 3 4 5 6 I begin my script with: par(mfcol=c(3,2)) par(oma=c(0,0,0,0)) -- This is for a postscript figure so I really don't need the outer margins. d=5 par(mar=c(d,d,d,d)) -- This applies to all the 6 plots. Now if d=0, plots 1-2,3-4 and 5-6 will have no gap between them and 1-3-5 and 2-4-6 will not have any spacing either. This is how I want it. But I also want y axis points and y label for 1, 3 and 5 and x axis points and labels for 5 and 6. With d=0, there is no space left for these labels. With d=5 (for ex.) I can have the labels but it also introduces a gap of 'd' text lines between the plots. I have tried: par(mar=c(0,d,0,0)) plot 1 par(mar=c(0,d,0,0)) plot 3 par(mar=c(d,d,0,0)) plot 5 par(mar=c(0,0,0,0)) plot 2 par(mar=c(0,0,0,0)) plot 4 par(mar=c(d,0,0,0)) plot 6 But in this approach, the plots are all not of the same size because of differences in margins and I want all the plots to be square and look similar when printed. Do have any comments or suggestions on how to go about doing it?

Re: [R] Multiple figures margin problem
Hello Greg, I tried that and got a similar result. The axes are still hidden. I am studying R Intro and Fig2A and 3B in http://research.stowers-institute.org/efg/R/Graphics/Basics/mar-oma/index.htm . They seem to indicate that the mar parameter alone controls the visibility of axis labels. Am I missing something obvious?

[R] Re-execute previous command
Hello All, In bash, to re-execute a command, say, 'gnuplot plot.gnu', one can type !gnu. Is there a similar feature in the R console? For example: plot(g1$mean,g2$mean) . . . Lines, many lines of commands -Here I want to repeat the previous plot command. !plot and plot(+TAB) do not work. This question was asked in this forum back in 2006 but the answer seems to have been lost somewhere in their discussions. This is the thread http://n4.nabble.com/R-command-line-need-intelligent-command-history-recall-td793072.html#a793075 . Can some one comment if there is a way to do it?

Re: [R] Conditional read-in of data
Hello Jim and Gabor,
Thanks for your inputs. The lines:
a-as.matrix(read.table(pipe(awk -f cut.awk Data.file)))
cut.awk{for(i = 1; i = NF; i=i+10) print $i,}
solved my problem. I know that 40k lines is not a large data set. I have
about 150 files each of which has 40k rows and in each file I wanted to
visualize (basically to ensure nothing odd is going on) how the data behaves
in each quarter of the data w/o making 150 figures/pdf files. In future as
my data size increases I will consider using relational databases.
Thanks again,
mnstn

1. You can pipe your data through gawk (or other scripting language)
process as in:
http://tolstoy.newcastle.edu.au/R/e5/help/08/09/2129.html
2. read.csv.sql in the sqldf package on CRAN will set up a database
for you, read the file into the database automatically defining the
layout of the table, extract a portion into R based on an sql
statement that you provide and then destroy the database all in one
statement. It uses the sqlite database which is included in the
RSQLite R package that it depends on so there is nothing to separately
install.
See ?read.csv.sql in the package and also see example 13 on the home page:

Any suggestions/comments are welcome.
