Changing aspect ratio for the plot about corrplot HOT 8 CLOSED

Could you come up with a minimal reproducible example ?

from corrplot.

sure!

M <- matrix(rnorm(70), ncol = 7)
corrplot(M, is.corr = F)

here the matrix is 10 x 7. I would like to get a plot with an aspect ratio 1:1 (for the main plot, not talking about labels and legends) and hence with the single panels having an aspect ration of 0.7:1.

from corrplot.

Would this be the desired output?

M <- matrix(rnorm(70), ncol = 7)
M2 <- matrix(0, nrow=10, ncol=10)
M2[,1:7] <- M
corrplot(M2, is.corr = F)

from corrplot.

Depends on what you mean. Yes, it is the desired output in the sense as here the core plot has an aspect ratio of 1:1, but no, I rather would not achieve this by adding empty columns.

I would like to get something were the small squares were not quadratic but rectangular so that the main plot would be quadratic. I used to produce a custom graphic that looked like this:

However I'd rather use corrplot as it looks nicer and requires much less code (on my side of things)

from corrplot.

I now understand. Do you also want the circles to be ellipses or circles centered inside the rectangles?

from corrplot.

In my fork, I've added a new parameter win.asp which controls the aspect ratio of the plotted matrix.
(now it only works for "circle" and "square" methods when win.asp != 1)

If @taiyun is ok with this, I can merge it into the main branch.
Example:

M <- matrix(rnorm(70), ncol = 7)
corrplot(M, is.corr = F, win.asp = .7)

from corrplot.

great! that's exactly what I was looking for!
