rggobi's Issues

NULL deprecated in .C()

I saw this warning and not sure if it is easy to fix:

> library(rggobi)
> ggobi_find_file('data', 'flea.csv')
[1] "/usr/share/ggobi/data/flea.csv"
Warning message:
In .GGobiC("getNumGGobiInstances", num = as.integer(-1), .gobi = NULL) :
  passing an object of type 'NULL' to .C (arg 2) is deprecated

capturing the current display

Here Michael Lawrence has provided a way to capture the current display of Ggobi, and after having used it, I can guarantee it works very well. It would be nice to include it in the package.

currentDisplay <- function(x) UseMethod("currentDisplay")
currentDisplay.GGobi <- function(x) {
 rggobi:::.GGobiCall("getCurrentDisplay", .gobi = x)
}

ggobi has migrated from homebrew core to homebrew/science

Trying to follow instructions in README and discovered this:

bug in ggobi_display_save_picture() for scatterplot matrix

Hello,

ggobi_display_save_picture(..., plot.only=TRUE) does not work for a scatterplot matrix.

There's a programming error here:

  if (inherits(display, "GGobiScatmatDisplay")) 
    display_widget1 <- display_widget[[2]][[1]]
  display_widget2 <- display_widget[[2]][[3]][["widget"]]

It should be replaced with:

  if (inherits(display, "GGobiScatmatDisplay")) 
    display_widget1 <- display_widget[[2]][[1]]
  else display_widget2 <- display_widget[[2]][[3]][["widget"]]
