i = 1 million = 1000000 while (i < million) { print('Thank you UQ Library') i = i + 1 }

😂 thank you!

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

how can we give annotations to row and columns using pheatmap in r studio? since I am new to use r studio

[@uqlibrary]

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

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

[@uqlibrary]

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!

[@JahidulIslam-eo4ng]

Thank you

[@elizabethquintero7024]

Good night. There is a way to make a ComplexHeatmap with only one gradient color? Thank you

[@uqlibrary]

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.
