Overlapping Field Names in mice::md.pattern

Question

Generating a graphic in R using the mice package using the md.pattern function to graph the rows and columns of a data.frame where there are missing data values. This function creates a plot pasted below. The field headers are overlapping and are illegible. I've tried expanding the parameters of the image but that doesn't change anything.
Any ideas on how I can work around this? Any insight is appreciated.

Answer 1

you can try this

md.pattern(x, plot = TRUE, rotate.names = TRUE)
