You can use the argument annotation_row and annotation_col for that. There is an example in this article: towardsdatascience.com/pheatmap-draws-pretty-heatmaps-483dab9a3cc
You could change change the colour scale for the "col" argument in the Heatmap() function. This dataset is not ideal, but just to give you an example, if you want a colour scale that goes from white to blue, you can do this: Heatmap(mtcars, col = circlize::colorRamp2(breaks = range(mtcars), colors = c("white", "blue"))) You will have to make sure you provide good breaks that work for the data you have, which is why I used the range() function to get the actual min and max for the dataset.
The ideal size and resolution will depend on how much information there is on the visualisation (i.e. how precise it is a how much data was used), so I don't have a definite answer to that, sorry!
Excellent video. Thank you very much. it was very useful :)
Excellent video, you know how to walk people through a tutorial and not assume knowledge.. excellent
Thank you very much, Ncedile :)
This is great. Best explained and detailed video for heatmap. Thanks a lot
Excellent tutorial, simple and easy walk on step-by-step. Thanks a lot.
Great tutorial!!!! I'll definitely look up those other websites you recommend! thank you so much!
Great video. Clear and precise explanation, thanks!
This was a really fantastic video on heatmaps. Thank you!
Thank you for the video. It is very helpful.
i = 1
million = 1000000
while (i < million) {
print('Thank you UQ Library')
i = i + 1
}
😂 thank you!
Bravo Stéphane.
thankyou
This is great. Thanks a million
Thanks a lot
thank you so much ! great work
there is no scaling option in geom_tile(), right? what is the best way to do it then?
Thank you for your videos
Could you make videos about Nnet and gstat packages?
Good luck
Thank you
how can we give annotations to row and columns using pheatmap in r studio? since I am new to use r studio
You can use the argument annotation_row and annotation_col for that. There is an example in this article: towardsdatascience.com/pheatmap-draws-pretty-heatmaps-483dab9a3cc
Good night. There is a way to make a ComplexHeatmap with only one gradient color? Thank you

What's the best size to save heatmap as a png?

Thank you
