corrmorrant: better correlation plots with ggplot2

The new corrmorrant #ggplot2 extension makes it easy to make #Correlation plots in #R, a critical skill for exploratory data analysis (EDA). We'll use corrmorrant to:

1. Make quick correlation plots in 1 line of code
2. Extend ggplot with the grammar for correlation plotting

Thanks for posting Matt, these Tuesday Tips are great at reminding me of packages I don't use often or new packages I should learn.

The ggplot2 package has been updated.
Could the author of corrmorant package update the code in accordance with the newest ggplot2 package? Thank you.

Looks cool but how much different it is from GGally’s ggpairs?

[alejandrotrujillo]

Can I put the p-value and the spearman correlation at the top of the diagonal at the same time? How?

Thanks a lot for corrmoate sugget; a great package. I had a little problem showing up: My variable-names are quite long. Can put an 90 degree angle to all the axis to flip the names?

Thanks. However, I got the following message while installing the first package. Please suggest to me how I solve it. Thanks in advance.
