When I download hexbin from Bioconductor and then use library(hexbin) I get the message that I should download the newest version. The old version is fine for what I want to do, except that I would like to add some points to the plot. e.g. an MA plot with controls highlighted plot(MA$A[,1],MA$M[,1],main="MA plot") points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) I want to replace the first plot command with hexbin (so I can actually visualize the dense region of the plot), but I want to be able to add my points to the plot. plot(hexbin(MA$A[,1],MA$M[,1]),main="MA plot") points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) does not give an error message. But the points do not show up. If the new version can do this, could someone please point me to the download site. Thanks, Naomi S.

Hi Naomi, You could try something like this, hbin<-hexbin(xx,yy,xbins=50) #hexbin plot pp<-plot(hbin,legend=FALSE) pushHexport(pp$plot.vp) x<-seq(4,13,length=100) #points you want to add y<-mysigma.rma.bio1(x) #to the hexbin plot grid.points(x,y,gp=gpar(col=2),pch=20) popViewport() Regards, Ariel./ On July 18, 2005 01:16 pm, Naomi Altman wrote: > When I download hexbin from Bioconductor and then use library(hexbin) I get > the message that I should download the newest version. > > The old version is fine for what I want to do, except that I would like to > add some points to the plot. > > e.g. an MA plot with controls highlighted > > plot(MA$A[,1],MA$M[,1],main="MA plot") > points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) > > I want to replace the first plot command with hexbin (so I can actually > visualize the dense region of the plot), but I want to be able to add my > points to the plot. > > > plot(hexbin(MA$A[,1],MA$M[,1]),main="MA plot") > points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) > > does not give an error message.

Thanks Ariel, I was not able to find pushHexport and it does not appear using help.search. --Naomi At 01:27 PM 7/18/2005, Ariel Chernomoretz wrote: >Hi Naomi, > >You could try something like this, > > hbin<-hexbin(xx,yy,xbins=50) #hexbin plot > pp<-plot(hbin,legend=FALSE) > > > pushHexport(pp$plot.vp) > x<-seq(4,13,length=100) #points you want > to add > y<-mysigma.rma.bio1(x) #to the hexbin plot > grid.points(x,y,gp=gpar(col=2),pch=20) > popViewport() > >Regards, >Ariel./ > > > >On July 18, 2005 01:16 pm, Naomi Altman wrote: > > When I download hexbin from Bioconductor and then use library(hexbin) I get > > the message that I should download the newest version. > > > > The old version is fine for what I want to do, except that I would like to > > add some points to the plot. > > > > e.g. an MA plot with controls highlighted > > > > plot(MA$A[,1],MA$M[,1],main="MA plot") > > points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) > > > > I want to replace the first plot command with hexbin (so I can actually > > visualize the dense region of the plot), but I want to be able to add my > > points to the plot. > > > > > > plot(hexbin(MA$A[,1],MA$M[,1]),main="MA plot") > > points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) > > > > does not give an error message.

Hi Naomi, pushHexport is included in new versions of hexbin package (for instance in hexbin 1.3.0 from the development branch) I am not an expert using grid but I think once you make the hexbin plot the current viewport (using pushHexport) you can use any function of the grid package on it (i.e. grid.points, grid.text, etc) A./ On July 18, 2005 01:38 pm, Naomi Altman wrote: > Thanks Ariel, > > I was not able to find > > pushHexport > > and it does not appear using help.search. > > --Naomi > > At 01:27 PM 7/18/2005, Ariel Chernomoretz wrote: > >Hi Naomi, > > > >You could try something like this, > > > > hbin<-hexbin(xx,yy,xbins=50) #hexbin plot > > pp<-plot(hbin,legend=FALSE) > > > > > > pushHexport(pp$plot.vp) > > x<-seq(4,13,length=100) #points you want > > to add > > y<-mysigma.rma.bio1(x) #to the hexbin plot > > grid.points(x,y,gp=gpar(col=2),pch=20) > > popViewport() > > > >Regards, > >Ariel./ > > > >On July 18, 2005 01:16 pm, Naomi Altman wrote: > > > When I download hexbin from Bioconductor and then use library(hexbin) I > > > get the message that I should download the newest version. > > > > > > The old version is fine for what I want to do, except that I would like > > > to add some points to the plot. > > > > > > e.g. an MA plot with controls highlighted > > > > > > plot(MA$A[,1],MA$M[,1],main="MA plot") > > > points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) > > > > > > I want to replace the first plot command with hexbin (so I can actually > > > visualize the dense region of the plot), but I want to be able to add > > > my points to the plot. > > > > > > > > > plot(hexbin(MA$A[,1],MA$M[,1]),main="MA plot") > > > points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) > > > > > > does not give an error message.

Hi, Haven't been checking the list for a while. what I think you want to do is look at the function plotMAhex in the new hexbin package. if that doesn't work for you you can try: hbp<-plot(hexbin(MA$A[,1],MA$M[,1]),main="MA plot") pushHexport(hbp$plot) grid.points(MA$A[mypoints,1],MA$M[mypoints,1],col=2) Nicholas
