Hello, I have been using R markdown and flexdashboard to make html / web page, and somehow the textboxes that are associated with the files that I read in R studio for maps (they are all shapefiles, and these appear after the function readOGR). I have yet to find a solution to make these textboxes disappear. Let me know if there is a way to solve this?
Try setting message=FALSE in your chunk header; it should make the "textboxes" go away
wasn't able to solve the problem just with message=FALSE,
but found another article on stackoverflow that set verbose=FALSE in the readOGR chunk. so like:
layers <- readOGR(dsn= , " " , verbose =FALSE)
so if anyone else have similar problem with unsuppressed texts, this may solve the problem.
You are right; I have out of curiosity checked the source code of
rgdal::readOGR() and it uses
cat() for printing the output. This means it can not be suppressed by
message = FALSE in chunk headers, as this works only for output printed by
I stand corrected.
BTW there is an interesting - if somewhat technical - discussion of the
message() issue on SO: https://stackoverflow.com/a/36700294/7756889
