Plotting multiple corrplots on same page

[cwilso6]

I would like to be able to plot multiple corrplots on the same page. Is there a recommended way to plot them using ggpubr or gridExtra packages, preferably ggpubr. Below is an example:

library(ggpubr)
data(mtcars)
M <- cor(mtcars)
set.seed(0)

##  different color series
col1 <- colorRampPalette(c("#7F0000", "red", "#FF7F00", "yellow", "white",
                           "cyan", "#007FFF", "blue","#00007F"))
col2 <- colorRampPalette(c("#67001F", "#B2182B", "#D6604D", "#F4A582",
                           "#FDDBC7", "#FFFFFF", "#D1E5F0", "#92C5DE",
                           "#4393C3", "#2166AC", "#053061"))
col3 <- colorRampPalette(c("red", "white", "blue"))
col4 <- colorRampPalette(c("#7F0000", "red", "#FF7F00", "yellow", "#7FFF7F",
                           "cyan", "#007FFF", "blue", "#00007F"))
wb <- c("white", "black")

par(ask = TRUE)

## different color scale and methods to display corr-matrix
plot1=corrplot(M, method = "number", col = "black", cl.pos = "n", title='cutoff')

ggarrange(plot1,plot1)

Which produces the following error:

Warning messages:
1: In as_grob.default(plot) :
  Cannot convert object of class matrix into a grob.
2: In as_grob.default(plot) :
  Cannot convert object of class matrix into a grob.

Again, I want to emphasize that my main goal is to use ggpubr or gridExtra

[cwilso6]

Is it possible to have both the matrix and the plot be output from corrplot? As of now, when I assign the plot to a variable it is a matrix. If I could access the plot object, then I think would able to use the desired packages.

You can try my R package ggcorrplot2, which currently implemented a subset of features of corrplot using ggplot2. Thus, you can combine multiple corrplots into one plot using cowplot or patchwork. See the following figure.

@caijun Your package looks great. However, for some reason, I can't install it. I tried various things but I keep getting "not available for 3.6.1..."

[caijun]

I haven't released ggcorrplot2 on CRAN, thus you are unable to install ggcorrplot2 via install.packages("ggcorrplot2") . Try to install ggcorrplot2 from github:

if (!requireNamespace("devtools")) install.packages("devtools")
devtools::install_github("caijun/ggcorrplot2")

[jukicivan]

Yes, of course, I realised that. I tried through install_github but then I stumbled upon api problem. This is apparently related to my corporate computer because it now worked on my private mac. However, I still have some issues as it seems that ggcorrplot cant recognise some of the functions that it contains. For example, title, hc.order or lab.

Error in ggcorrplot(cor2, type = "upper", p.mat = p.mat2, hc.order = TRUE, : unused arguments (hc.order = TRUE, title = "Females")

[caijun]

ggcorrplot2 currently has implemented only a subset of features that corrplot has. The parameters hc.order and title are not supported yet. Please see the document of ggcorrplot().

With patchwork and gridGraphics you can plot multiple corrplots easily with the function wrap_elements. You can do something like:

p1 = wrap_elements(~corrplot(M, method = "number", col = "black", cl.pos = "n", title='cutoff'))
p2 = wrap_elements(~corrplot(M))

p1 + p2
