replace string values with numbers
Hi everyone, I have a data frame Gene with SNPs eg. P1 P2 P3
CG CG GG
-- -- AC
-- AC CC
AC -- AC I tried to replace all the GG with a value 3. Gene[Gene=="GG"]<-3 It always give me: Warning in `[<-.factor`(`*tmp*`, thisvar, value = 3) :
invalid factor level, NAs generated Does any know if there is anything wrong with my code? Thanks, Zhengyu

Ask for help: find corresponding elements between matrix
Dear R experts,
I have two matrix (seq & mat) & I want to retrieve in a new matrix all the numbers from mat that =1 (corresponding to the same row/ column position) in seq, or all the numbers in mat that =-1 in seq. - Replace all the numbers with NA if it's not 1/-1 in seq. There are some "NA"s in seq.
seq=matrix(c(1,-1,0,1,1,-1,0,0,-1,1,1,NA),3,4)

Why does smoothScatter clip when xlim and ylim increased?
Hi:
Is there a way to get smoothScatter to not clip when I increase the xlim and
ylim parameters?
Consider the following example:
set.seed(17)
x1<-rnorm(100)
x2<-rnorm(100)
smoothScatter(x1,x2)
#Now if I increase xlim and ylim notice that the plot seems to be clipped at
the former xlim, and ylim boundaries:
smoothScatter(x1,x2, xlim=c(-5,5), ylim=c(-5,5))
Thanks.

smoothScatter
Hi, I have been trying to plot density plots using the example on:
http://addictedtor.free.fr/graphiques/graphcode.php?graph=139
I used to use this function, but I cannot get any old code or even the example to work.
library("geneplotter")
require("RColorBrewer")
x1 <- matrix(rnorm(1e4), ncol=2)
x2 <- matrix(rnorm(1e4, mean=3, sd=1.5), ncol=2)

smoothScatter problems
Hello,
I'm having some trouble getting a good result for a smoothScatter plot.
I have some data that I want to log-plot, but when I use smoothScatter
the result is not correct.
The problem seems to be that with the log="x" argument smoothScatter
calculates the bins linearly, so the plot will be skewed towards the right.
See for example:

smoothScatter function question and adding a legend
Hello,
I have a few questions, regarding the smoothScatter function.
I have a scatter plot with more than 500,000 data points for
two samples. So, I am wanting to display the density in colors
to convince people that my good correlation coefficient is not
due to an "influential point effect" and plus, I also want to make
my scatter plot look pretty. Anyway ...

reversing xlim, ylim in smoothScatter
Hello,
I have found that in smoothScatter it is not possible to reverse the axes plotted (R version 2.9.0) . It appears that this arises from the hard coding of xlim and ylim in smoothscatter.R in the lines :
x <- x[ xlim[1] <= x[,1] & x[,1] <=xlim[2], ] (line number 25)
and
x <- x[ ylim[1] <= x[,2] & x[,2] <= ylim[2], ] (line number 31)
This results in a x

density plot on a log scale
I'm working with a large dataset - large enough that when I do a scatter plot
the points all blur together, so I want to plot their density by color - a
heat map or something like that. I've used smoothScatter for tasks like
this, but the problem is that my current dataset really only looks good on a
log-log scale. When I do the following command

SmoothScatter plot range issue
Hello,
I am attempting to use smoothScatter to plot a heatmap of locations of
events in an x-y axis. When I plot the heatmap without passing xlim and ylim
parameters, it fills the plot area but the perspective is a bit skewed. I
would like to standardize these plots to a uniform window size that does not
depend on the range of values in the dataframe. However, when I resize the
plot using xlim or

Saving estimates after nested loops
Hi R-listers,
Savings regression results after a loop is straightforward. But what about when you have nested loops?
I am running a regression of the form
lm(y~1+x+M+ D[,i] + D[,j] + D[,k])
where x is the variable of interest. M and D are vectors with other covariates.
Vectors "M" and "x" are included in every regression. Then i loop over the columns of D to use all

Is there a way to avoid loading dependendent packages?
Hello R help list
I have been using the smoothScatter function within the "geneplotter"
package to make some graphs using a Sweave Rnw script called via Rscript
in a DOS/Windows batch file. The Rscript will ultimately be called by a
web service with time-out constraints, hence things need to run as
swiftly as possible.
The geneplotter package is currently loaded each time R is invoked

smooth scatterplot and geo map
Hello everybody,
I'm trying to understand how to draw a smoothed scatterplot on a geographic
map with R.
Have a dataframe with point locations (long, lat) and was able to simply
plot these points on a shp map by using the maptools package. However,
instead of having simply the raw points on the map, I would like to have a
"smoothed" scatterplot of the same superimposed on the map.

plot matrix
Dear R users,
I like to plot a matrix A which looks like this:
,1 ,2 ,3 ,4
1, 1 10 100 1000
2, 0.5 0.2 1.0 4.3
3, 0.1 0.2 0.3 0.5
.....
where the 1st row is representing the X-axis values. The subsequent
rows should be plotted on the y-axis. I would prefer to use the
smoothScatter plotting function of the geneplotter package, but to
begin with R I'd be happy to use

Extending RAIDZ.
Yeah:)
I''d like to work on this. Here are my first observations:
- We need to call vdev_op_asize method with additonal ''offset'' argument,
- We need to move data to new disk starting from the very begining, so
we can''t reuse scrub/resilver code which does tree-walk through the
data.
Below you can see how I imagine to extend RAIDZ. Here is the legend:

image quality
dear all,
I am writing a sweave documentation for my analysis, and I am plotting huge
scatter plot data for microarray.
unlucly this take a lot of resource to my pc because of the quality of the
image which is to high (I see the PC get stuck for each single spot).
how can I overcome this problem? is there a way to make lighter image?

Lattice plots for images
Hello UseRs,
I need help on how to plot several raster images (such as those obtained
from a kernel-smoothed intensity function) in a layout
such as that obtained from the lattice package. I would like to obtain
something such as obtained from using the "levelplot" or "xyplot"
in lattice. I currently use:

to set the workspace, but the resulting plots
