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

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 ...
I have been able to

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).

Running examples in ?EDASeq-Ex.R? failed

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

Hi, I have been trying to plot density plots using the example on:

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 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

strange behaviour of importFrom directive in name space

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

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)

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.

smoothScatter on map
Hello everybody,
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
long 15W-30E.

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

Binning Question
Hi,
I'm trying to setup some complicated binning with statistics and could
use a little help.
I've found the bin2 function from the ash package, but it doesn't do
everything I need. My intention is to copy some of their code and then
modify as needed.
I have a vector of two columns:
head(data)

contourplot lines, text, and mtext
If I have a contourplot (in the lattice package) and I want to add
straight lines to it, how do I do this?
I see that there are llines() and lsegement() functions for lattice
plots, but they don't seem to do anything in this case:
library(lattice)
library(KernSmooth)
x=rnorm(10000)
y=x+rnorm(x,0,.5)
a=bkde2D(cbind(x,y),.7)
z=as.vector(a$fhat)

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.

ugly plots with xlim/ylim exceeding data range (changed since R2.6.1)
The behaviour of the plot function when used with xlim/ylim and the
matplot function as in the following simple example changed between
R2.6.1 and 2.7.0+ producing ugly plots in the new versions. In case of
plot it looks like the pretty function is called with wrong arguments
(i.e. range of supplied data rather than values of xlim and ylim):
m = matrix(c(-0.033, 0.009, 0.064, 0.050, 0.097,
