An error occurs when all the off-diagonals of the input of corrplot.mixed are NAs #154

corrplot.mixed fails when all the off-diagonals of the input matrix are NAs. However, corrplot runs successfully under the same condition.

Example:

(m1 <- matrix(c(1, 0.5, NA, 0.5, 1, NA, NA, NA, 1), nrow = 3))
#>      [,1] [,2] [,3]
#> [1,]  1.0  0.5   NA
#> [2,]  0.5  1.0   NA
#> [3,]   NA   NA    1
(m2 <- matrix(c(1, NA, NA, NA, 1, NA, NA, NA, 1), nrow = 3))
#>      [,1] [,2] [,3]
#> [1,]    1   NA   NA
#> [2,]   NA    1   NA
#> [3,]   NA   NA    1
library(corrplot)
#> corrplot 0.84 loaded
corrplot(m1)

corrplot(m2)

corrplot.mixed(m1)

corrplot.mixed(m2)
#> Error in symbols(Pos, add = TRUE, inches = FALSE, rectangles = matrix(1, : invalid symbol coordinates
