feature request: bar plot of median for 'add_col_summary' and 'add_row_summary'

[IgnatiusPang]

Dear Ms. Schep,

Currently, the 'add_col_summary' and 'add_row_summary' add a bar plot to the margin of the heat map. The bar plot would indicate the mean value for each column or row, but only the mean value is available. Would it be possible to enable to the user to plot the 'median' value for the bar plot instead please? Even better, it may be useful to let the user to choose which function to use for the bar plot (e.g. sd, var, median, mad etc...).

The package is very useful and I'm already using it for my projects! Thank you! Looking forward to read the paper associated with it.

Yours Sincerely,

Ignatius Pang

Hi Ignatius,

Great suggestion -- I think that'd be a nice feature to add. I think there could be an argument that would default to the function mean but someone could add in their own summary function if desired, such as median or even a custom function.

Actually custom summary functions might be tricky, would have to think about handling different optional arguments and validating that they actually are summary functions. For now, I am going to add in support for 'mean','median','sd','var','mad','min', and 'max' via a summary_function argument.

Thank you Alicia. I agree with adding support for a limited number of functions. I think having these commonly used functions will be very helpful already =)

Great, these options are now in iheatmapr, so closing this issue!
