r中带有ggplot2的多个图

Question

I have a list of 12 dataframes:

[1] X2016_kvish_1_10t
[2] X2015_kvish_1_10t
[3] X2014_kvish_1_10t
[4] X2013_kvish_1_10t
[5] X2012_kvish_1_10t
[6] X2011_kvish_1_10t     
# with 6 more ...    

and I want to plot them with the multiplot function (ggplot2). for example, this is a single plot:

ggplot(data = X2015_kvish_1_10t) +
geom_line(mapping = aes(
x = date, y = X2015_kvish_1_10t$nefah), colour = "blue") + 
ylab("Traffic Counts (quantity)")+ ggtitle("Traffic Counts")+
geom_point(mapping = aes(
x = date, y = X2015_kvish_1_10t$day_mean , color = "blue"))

how can I plot them together so I can see the 12 at the same time and I won't need to write the same functions 12 times ?

Answer 1

if p is your plot, and ld the list of data.frames, you could do:

grid.arrange(grobs = lapply(ld, "%+%", e1 = p))

(untested, for lack of reprex)

But note that you should never have $ inside aes() . And, of course, facetting is probably the better option.
