Error message when drawing network plot

[r0sies]

Hi,

When visualising the transmission links as a network, I receive the below error.
I have generated network plots using the same code for several mrsa and one vre clusters, however for two other vre clusters I am receiving the below error. Are there any ways around this? Thanks.

load("raw_dates_vre.RData")
load("res_vre.RData")

node labels

dates <- raw_dates$date
names(dates) <- raw_dates$name
labels <- names(dates)

network plot

p <- plot(res, type = 'network') %>% visNodes(font = list(size = 20))
Error in $<-.data.frame(*tmp*, "arrows", value = "to") :
replacement has 1 row, data has 0

p <- plot(res, type = 'network', min_support=0.01) %>% visNodes(font = list(size = 20))
Error in $<-.data.frame(*tmp*, "arrows", value = "to") :
replacement has 1 row, data has 0

Hi - I suspect this may be because no links in your network are above the minimum support (even if you've set it to 0.01). Could you try setting it to 0 just to check if that solves the problem? If that's the error, I'll make sure to provide a more informative error message.
