kandi X-RAY | ChIPseeker Summary
This package implements functions to retrieve the nearest genes around the peak, annotate genomic region of the peak, statstical methods for estimate the significance of overlap among ChIP peak data sets, and incorporate GEO database for user to compare their own dataset with those deposited in database. The comparison can be used to infer cooperative regulation and thus can be used to generate hypotheses. Several visualization functions are implemented to summarize the coverage of the peak experiment, average profile and heatmap of peaks binding to TSS regions, genomic annotation, distance to TSS, and overlap of peaks or genes.

QUESTION
I have a list of data.frames called tagMatrixList from the package ChIPseeker. Is there a way to generate tagHeatmap (tagMatrixList, xlim=c(-3000, 3000), color="blue") for each data frame and then save each single plot in a file? Thank you in advance.

ANSWER
Answered 2020-May-11 at 13:30You need to open up a image device to save the plot to it (such as png(), pdf(), etc.), and then close it with dev.off() when you're done.
Since your list doesn't have names and you want a file for each plot, we'll loop over a vector of numbers instead to both index the object, and add a file name with that index number.
