plot - Plotting multiple histograms quickly in R -


for exploratory analysis, useful plot multiple variables in 1 grid. easy way to:

hist(mtcars[c(1,2,3,4)])

however, becomes difficult adjust breaks , axes maintain consistency i.e.

hist(mtcars[c(1,2,3,4)], breaks = 10)

does not effect histograms. there easy work around or easy way in ggplot2?

this how hist() : 

lapply(mtcars[1:4], fun=hist)

however prefer store plots in r objects ggplot2 , display plot lists cowplot::plotgrid() :

list <-lapply(1:ncol(mtcars),               function(col) ggplot2::qplot(mtcars[[col]],                                            geom = "histogram",                                            binwidth = 1))  cowplot::plot_grid(plotlist = list)
