ggplot2 - problems with arrangeGrob under R version 3.2.2 -

i 've updated r version including packages , function arrangegrob (package gridextra) has changed.

on old version r version 3.1.3 used following make corner labels:

loading r packages

library(ggplot2) library(grid) library(gridextra) 

example data

a <- 1:20 b <- sample(a, 20) c <- sample(b, 20) d <- sample(c, 20) 

create data frame

mydata   <- data.frame(a, b, c, d) 

create example plots

myplot1  <- ggplot(mydata, aes(x=a, y=b)) + geom_point() myplot2  <- ggplot(mydata, aes(x=b, y=c)) + geom_point() myplot3  <- ggplot(mydata, aes(x=c, y=d)) + geom_point() myplot4  <- ggplot(mydata, aes(x=d, y=a)) + geom_point() 

set corner labels

 myplot1 <- arrangegrob(myplot1, main = textgrob("a", x = unit(0, "npc")      , y   = unit(1, "npc"), just=c("left","top"),      gp=gpar(col="black", fontsize=18, fontfamily="times roman")))   myplot2 <- arrangegrob(myplot2, main = textgrob("b", x = unit(0, "npc")      , y = unit(1, "npc"), just=c("left","top"),      gp=gpar(col="black", fontsize=18, fontfamily="times roman")))   myplot3 <- arrangegrob(myplot3, main = textgrob("c", x = unit(0, "npc")     , y  = unit(1, "npc"), just=c("left","top"),     gp=gpar(col="black", fontsize=18, fontfamily="times roman")))   myplot4 <- arrangegrob(myplot4, main = textgrob("d", x = unit(0, "npc")     , y = unit(1, "npc"), just=c("left","top"),     gp=gpar(col="black",    fontsize=18, fontfamily="times roman")))   grid.arrange(myplot1, myplot2, myplot3, myplot4)  

and got following plot, fine:

but under new r version 3.2.2 image looks this:

arrangegrob opens every textgrob new image , got 8 images on 1 page instead of four. how can fixed plot looks in old version of r , gridextra?

from kev's comment:

there has been rewrite of gridextra, not (fully) backward compatible - may issue. have @ new wiki cran.r-project.org/web/packages/gridextra/vignettes/… . try changing main top – user20650
