selectROI: wrong position

[marco.gi...@gmail.com]

Hi, I try to select ROI from the mse dataset using 

image(mse, mz=1200)

ROI1 <- selectROI(mse, mode="region")

but when i select in a specif position, the script tale the region from another and unwanted position. 

I am using Rstudio.

Somebody had the same issue of mine

thank you 

Marco

the problem has been solved... it was a problem regarding the resolution of my display. The display zoom in Rstudio has to have the same value of monitor's one.

Hi Marco,

I bumped into a very similar problem (the ROIs I select on screen (Plots pane) are off and end up being empty (Zoom Plots pane)).

see screenshot:

could you please share how exactly you solved the issue?

thanks in advance!

Found a solution (for macOS) as follows using quartz:

#pop the plotting area out of rstudio
graphics.off()
quartz()

#then roi ROI selection tool

image(mydata_sample)

 current_selection <- selectROI(mydata_sample)

Yes, it is an issue with the RStudio graphics device; its coordinates can be sensitive to zooming and resizing.

You should be able to use windows() on Windows or X11() on Linux (versus quartz() on macOS).
