Hi David, thanks, yes, heatmap provides clustered heatmap, and I am looking for an unclustered display of a matrix, and only to set up the color ranges. thanks for your help ! -- bogdan On Fri, Jun 12, 2015 at 5:36 PM, David Winsemius <dwinsemius at comcast.net> wrote:> > > On Jun 12, 2015, at 5:28 PM, Bogdan Tanasa wrote: > > > Dear all, > > > > please could you advise about the most convenient functions or libraries > to > > use in order to display a matrix as a heatmap/a color matrix ? > > > > the matrix contains the values of 0, 10, 20, 30 or 100. thank you ! > > What?

Hi Bogdan, Have a look at color2D.matplot in the plotrix package - it's a bit different from "image" and "heatmap".

Thanks, Jim. Yes, a good idea, shall I find more time, typically all these little projects I am doing or asking are in big rush. Found some good tutorials about heatmap.2 too: http://www.inside-r.org/packages/cran/gplots/docs/heatmap.2 http://sebastianraschka.com/Articles/heatmaps_in_r.html On Fri, Jun 12, 2015 at 8:41 PM, Jim Lemon <drjimlemon at gmail.com> wrote:> Hi Bogdan, > Have a look at color2D.matplot in the plotrix package - it's a bit > different from "image" and "heatmap". > > Jim > > > On Sat, Jun 13, 2015 at 10:39 AM, Bogdan Tanasa <tanasa at gmail.com> wrote: > > Hi David, thanks, yes, > > > > heatmap provides clustered heatmap, and I am looking for an unclustered > > display of a matrix, and only to set up the color ranges. thanks for your > > help ! > > > > -- bogdan > > > > On Fri, Jun 12, 2015 at 5:36 PM, David Winsemius <dwinsemius at comcast.net > > > > wrote: > > > >> > >> > >> On Jun 12, 2015, at 5:28 PM, Bogdan Tanasa wrote: > >> > >> > Dear all, > >> > > >> > please could you advise about the most convenient functions or > libraries > >> to > >> > use in order to display a matrix as a heatmap/a color matrix ? > >> > > >> > the matrix contains the values of 0, 10, 20, 30 or 100. thank you ! > >> > >> What?

Thanks, David, for your time. I found some good tutorials on heatmap.2 and it works : https://www.packtpub.com/books/content/creating-your-first-heat-map-r On Fri, Jun 12, 2015 at 9:12 PM, David Winsemius <dwinsemius at comcast.net> wrote:> > On Jun 12, 2015, at 5:39 PM, Bogdan Tanasa wrote: > > > Hi David, thanks, yes, > > > > heatmap provides clustered heatmap, and I am looking for an unclustered > display of a matrix, > > Please explain what "clustered" means in the context of a heatmap. > > > and only to set up the color ranges. > > And that needs an explanation as well. > > > thanks for your help ! > > > > -- bogdan > > > > On Fri, Jun 12, 2015 at 5:36 PM, David Winsemius <dwinsemius at comcast.net> > wrote: > > > > > > On Jun 12, 2015, at 5:28 PM, Bogdan Tanasa wrote: > > > > > Dear all, > > > > > > please could you advise about the most convenient functions or > libraries to > > > use in order to display a matrix as a heatmap/a color matrix ? > > > > > > the matrix contains the values of 0, 10, 20, 30 or 100. thank you ! > > > > What?
