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

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 ...

smoothScatter plot
Hi, I want to make a plot similar to sm1 (attached). The code I tried is: dcols <- densCols(x,y)
smoothScatter(x,y, col = dcols, pch=20,xlab="A",ylab="B")
abline(h=0, col="red")
But it turned out to be s1 (attached) with big dots. I was wondering if anything wrong with my code. Thanks,Zhengyu

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

strange behaviour of importFrom directive in name space
Dear listers,
After activating the name space for my bioconductor package (prada) I
successfully ran R CMD check. However when loading the package in R and
running the examples the imported function brewer.pal from package
RColorBrewer is not found. I can directly call brewer.pal from the
RColorBrewer name space typing RColorBrewer::brewer.pal, but it is not

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:

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.

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

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

Determining Legend for smoothScatter
Dear all,
I am using the smoothScatter function in base R for a plot -
Lab.palette.both <-
colorRampPalette(c("darkblue","lightblue","red","yellow"), space = "Lab")
smoothScatter(X24fresh.sorted[,c(13,10)], colramp = Lab.palette.both)
I understand that my yellow colored points represent highest density, red
lower, lightblue even lower etc.

scatterplot3d with densCols ?
Hi,
I was trying to make a 3D plot using densCols. The documentation for
densCols doesn't look like it'll work for 3D. For example:
-----------------------------------------
library(scatterplot3d)
v1 <- rnorm(10000)
v2 <- rnorm(10000)
v3 <- rnorm(10000)
## 2D with denscols
mat1 <- cbind(v1,v2)
mcols1 <- densCols(mat1)
plot(mat1,col=mcols1)
mat <- cbind(v1,v2,v3)

densCols: what are the computed densities and how to create a legend
Hi,
I'm using the densCols function for a scatterplot and cannot figure out 1) how to extract the computed densities, and 2) how to create a legend based that represents the upper and lower ranges of the densities.
For example:
movers.den <- densCols(move$x, move$y)
table(movers.den)

smoothScatter() and the KernSmooth package
Dear R-devel,
my Bioconductor EDASeq package has a function MDPlot that uses the
smoothScatter() function from the graphics package. When I test this
package on travis-ci.org (R CMD check) I get the following error
(which I don't get on my machine nor on the Bioconductor build
system).

Bivariate Partial Dependence Plots in Random Forests
Hello,
I was wondering if anyone knew of an R function/R code to plot bivariate
(3 dimensional) partial dependence plots in random forests (randomForest
package).
It is apparently possible using the rgl package
(http://esapubs.org/archive/ecol/E088/173/appendix-C.htm) or there may
be a more direct function such as the pairplot() in MART (multiple
additive regression trees)?

smoothScatter on map

I'm here with a question concerning obtaining a greographical map with a
smmothed scatterplot overlaying the intersted regions.
My data are a set of opints, represented by long, lat coordinates. As far as
the map is concerned, a shp file of Europe without countries borders (only
coastal outlines) with the limits at lat 35N-60N

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

Graphing: plot 3rd variable based on color gradient
Hello,
I am searching for the best method to plot two variables with points
whose output color depends on the size of a third variable. For
example, the darkness of the x-y point would increase incrementally
based on the size of the z value, similar to the colramp parameter in
geneplotter. This would be analagous to symbols(), except changing the
selection from the color gradient rather than the

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?
