Could not find function default_missing

[cwibrand]

Hi!

I'm trying to get ggalluvial to work and remaking the vaccinations plot from the vignette. However, I'm getting the following error message. Any ideas of what might be wrong? I'm stumped...

ggplot(vaccinations,

• aes(x = survey, stratum = response, alluvium = subject,
• y = freq,
• fill = response, label = response)) +
• scale_x_discrete(expand = c(.1, .1)) +
• geom_flow() +
• geom_stratum(alpha = .5) +
• geom_text(stat = "stratum", size = 3) +
• theme(legend.position = "none") +
• ggtitle("vaccination survey responses at three points in time") Warning messages: 1: Computation failed in stat_flow() Caused by error in summarise(): ℹ In argument: lode = (function (x, order_by = NULL, default = default_missing(x)) .... ℹ In group 1: alluvium = 1, x = 1, yneg = FALSE, stratum = Missing, deposit = 1, fissure = 1, link = 1, flow = from, adj_deposit = 1.1.5, adj_fissure = 1.1.1. Caused by error in default_missing(): ! could not find function "default_missing" 2: Computation failed in stat_stratum() Caused by error in default_missing(): ! could not find function "default_missing" 3: Computation failed in stat_stratum() Caused by error in default_missing(): ! could not find function "default_missing"

Hi @cwibrand, this issue should be resolved soon; i'm in the process of sending a patch to CRAN. See #107 and #108 for details.

I'll close this issue as 0.12.5 is on CRAN and the other two issues document the problem and my understanding of it, but please do reopen if you install 0.12.5 and encounter the same or a related problem!
