network_plot() colours not correct if only positive correlations are plotted

[drsimonj]

network_plot() with only positive correlations shown result in red paths being drawn. E.g., try mtcars %>% correlate() %>% network_plot(min_cor = .9)

This is probably because the colours are not explicitly assigned.

Hi,
for me network_plot returns the following error message:

Error in function_list[[k]](value) : 
  could not find function "network_plot"

Hi @mhnierhoff, are you using the latest development version (0.1.0.900)?

If not, install via:

install.packages("devtools")
devtools::install_github("drsimonj/corrr")

[mhnierhoff]

Hi @drsimonj thanks for your quick reply. I installed the lastest dev version and the error messages does not pop up. But now the plot is just empty in the RStudio plot pane and the correlations for the network plot only become visible when I click on the Export button.

Oh - I found out that the visbility of the correlation lines depends on the pane size for plots. I just moved RStudio to another screen and made the right panes smaller and et voila the network lines are now visibile. But I don't think that this behavior is intended. ;)

[drsimonj]

Thanks @mhnierhoff. The plot is being made with ggplot2, so I'm not sure if it's something specific to network_plot() or ggplot2. I'll keep an eye on this and see if this behaviour can be fixed.
