R Psych软件包：通过变量的多个直方图标签

Question

I am ploting a multiple histogram for 5 variables, and I have the same title repeated along all of them. I didn´t find a way to personalize it for each histogram. Is there a way to do it? I am using the psych R package. Maybe another package to recommend?

The code line:

multi.hist(AutosCompleteNorm[,11:15],main="bah")

And "bah" is repeated 5 times. I tried c("a","b",..."e") as an argument but it didn´t work.

Package documentation:

https://www.rdocumentation.org/packages/psych/versions/1.8.3.3/topics/multi.hist

Thanks!

The current psych package doesn't seem to support this, which is strange because it would have been a natural feature for such a plot.

For customizability, I recommend you to take a look at ggplot and then layout in the format you wish using gridExtra .

Here's the code to create the few histogram in ggplot :

library(ggplot2)
p1 <- ggplot(vids, aes(x=log(likes)))+geom_histogram()+labs(title="title1")
p2 <- ggplot(vids, aes(x=log(dislikes)))+geom_histogram()+labs(title="title2")
p3 <- ggplot(vids, 
aes(x=log(comment_count)))+geom_histogram()+labs(title="title3")

And then laying them up in a 2 row layout ( nrow=2 ):

library(gridExtra)
grid.arrange(p1, p2, p3, nrow = 2)

Changing the layout to nrow=1 :

Following these comments, I just updated psych so that multi.hist is more useful.

You can now specify the margins for the plots, and it will, by default label each plot with the variable name.

I have not pushed the development version of psych (1.8.9) to CRAN yet, but it is available on my repository at

install.packages("psych",repos="https://personality-project.org/r",type="source")
