FW: how to enclose two xyplot
Dear R-users,
I have to plot two xyplot, and I wish to enclose this two graphs with just one headline, the same x scale, the same grid etc.
These parameters should tie in, in order to obtain, visually, a unique graph formed by two xyplot.
I try to give an idea:
xyplot1: |_|_|_|
xyplot2: |_|_|_|
what i want: | | | |
|_|_|_|
I tried to use the command

histogram with mean for every break
Dear R-users,
I need to produce a histogram where for every breaks there are the mean of the data.
I tried tu use the function >hist(x, break=20 ... ) but this return the numerosity for every breaks, not the mean.
Any hint?
Thanks in advance,
francesco

par and complex graph
Dear R-Users, I'd like to have some tips about printing graph.
I use the command par to print more graphs in one window:par(mfrow=c(6,1)); par(oma=c(2.5, 2.5, 2.5, 2.5)); par(mar=c(0.5,4, 0.5, 0.5))
But this command doesn't run with complex graphic command (i.e. xyplot, ternaryplot).How can I print more than one graph per page, when I work with this "elaborated" graph?Many

align xyplot
Dear R users,
I'm using xyplot to obtain a graph about a correlation x~y for different years (a categoric variable).
The program dispose automatically the graphs in this way:

vectors comparison
Dear R-Users,
I'd like to have your help on this problem:
I have two vectors:x<- c(0,1,0,0,0,0,0,0,0,0,0,1,0)y<- c(0,0,-10,0,0,-10,0,-10,0,0,0,0,0)
And I want to know where the value -500 in y have a correspondence value 1 in x.Considering a buffer of one position before and after in x.i.e. in this example only the -10 in position y[3] satisfies the criteria, because x has in position

Ternary plot and filled contour
Dear R-Users, I'd like to have some tips for a ternaryplot ("vcd").
I have this dataframe:

lm() and post hoc test
Dear Alex,
I have read your question about post-hoc test:
"Let's assume that according to Anova(lm(y~a*b, data=d)) the a:b interaction is significant, and I would like to know if there are specific combinations of a and b levels that differ from the control group. Are there any caveats against simply looking at the p-values in the output generated by summary(lm(y~a*b,data=d))? The

is there a packge or code to generate markov chains in R
Hi,
if i have data in the following time series format:
time, amount, state
1 2222 A

where states could be n and time periods t is there a package in R that would calculate the transition probabilities in a markov chain.
for each t except t=0 to generate
