[R] How to disable verbose grob results in pdf when using knitr with gridExtra?

[vod vos]

Sorry for no reproducible example.



using warnings=FALSE chunk options in knitr does not help. I found it is not the knitr's business.  I used 



resultpdf<- grid.arrange(facetpoint1,pright1,pright2,pright3,pright4,pright5,pright6,pright7, ncol=2, layout_matrix=cbind(c(1,1,1,1,1,1,1),c(2,3,4,5,6,7,8)), widths=c(2,1)) 



then 



print(resultpdf)



in my chunk.



I removed object resultpdf, just used code below to produce figure



grid.arrange(facetpoint1,pright1,pright2,pright3,pright4,pright5,pright6,pright7, ncol=2, layout_matrix=cbind(c(1,1,1,1,1,1,1),c(2,3,4,5,6,7,8)), widths=c(2,1)) 



then no verbose appeared.



The problem is using print() with ggplot2.

Keep in mind that this list is about R first and foremost. There is a 

mailing list for Knitr, and also the maintainer of the knitr package 

recommends asking questions on stackoverflow.com.

This is not a reproducible example. No matter where you ask this question 

you need to supply a complete short script that exhibits the problem. That 

also means including enough data IN THE SCRIPT to allow the script to 

run. There are multiple guides online that describe how to do this in 

detail.

None of this appears when I created my own reproducible R example: 

 

#### begin code 

library(grid) 

library(gridExtra) 

 

facetpoint1 <- pright1 <- pright2 <- pright3 <- pright4 <- pright5 <- 

pright6 <- pright7 <- textGrob("X") 

grid.arrange( facetpoint1, pright1, pright2, pright3, pright4, pright5 

 , pright6, pright7 

 , ncol=2 

 , layout_matrix = cbind( c( 1, 1, 1, 1, 1, 1, 1 ) 

 , c( 2, 3, 4, 5, 6, 7, 8 ) ) 

 , widths = c( 2, 1 ) 

 ) 

#### end code 

 

If the above example produces output for you in R or in a knitted PDF then 

something is different about your setup than mine.

Does this happen at the R console? If it does, please post a reproducible 

example, and the invocation and output of sessionInfo() (mine is below). 

If it doesn't, there could be some interaction with knitr going on, and 

using the echo=FALSE or warnings=FALSE chunk options could help, or you 

may need more specialized help than we can offer here (e.g. via one of 

the knitr support areas mentioned above).

When you don't set your email to plain text, the automatic conversion of 

HTML to text is very likely to cause us to see something quite different 

than you were looking at. It is in your best interest to figure out how to 

set your email program to send plain text. Please read the Posting Guide:
