changing k/digits argument doesn't make any difference to ggcorrmat plot correlations

[IndrajeetPatil]

This should display correlations with 3 digits after the decimal point.

# for reproducibility
set.seed(123)

# as a default this function outputs a correlalogram plot
ggstatsplot::ggcorrmat(
  data = ggplot2::msleep,
  corr.method = "robust",                    # correlation method
  sig.level = 0.001,                         # threshold of significance
  p.adjust.method = "holm",                  # p-value adjustment method for multiple comparisons
  cor.vars = c(sleep_rem, awake:bodywt),     # a range of variables can be selected  
  cor.vars.names = c("REM sleep",            # variable names
                     "time awake", 
                     "brain weight", 
                     "body weight"), 
  matrix.type = "upper",                     # type of visualization matrix
  digits = 3,                                # no. of digits after decimal point
  colors = c("#B2182B", "white", "#4D4D4D"), 
  title = "Correlalogram for mammals sleep dataset",
  subtitle = "sleep units: hours; weight units: kilograms"
)

I'll look at this next.

Okay I chased this one down. It's not your code. It works perfectly every where you control but fails when you get to line 390 and call ggcorrplot. Even if I try and deliberately pass it some number of digits it does not honor the call. So I tried calling it direct at the command line using the author's examples and it fails there too. Please see reprex.

library(ggcorrplot)
#> Loading required package: ggplot2
library(dplyr)
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':

#>     intersect, setdiff, setequal, union
# Almost identical to help file example just selecting columns
corr <- mtcars %>% dplyr::select(mpg,hp,wt) %>% cor
ggcorrplot(corr, 
           type = "lower", 
           insig = "blank", 
           lab = TRUE, 
           digits = 4)

Thanks. I've made a PR (kassambara/ggcorrplot#16) there which should fix this.
