error with syn on data with labels

[hjvdwijk]

Using syn on data with labels causes an error, for example this small dataset below. This error also can occur with other methods for larger data sets.

data <- tibble(id = c(1,2,3),
val = c("1","1","0"))
val_label(data$val,"0") <- "No"
val_label(data$val,"1") <- "Yes"
synth <- syn(data, method = "sample")

Error: Can't subset elements that don't exist.
x Locations 1, 2, and 3 don't exist.
i There are only 0 elements.

Many thanks for reporting the issue. The bug has been removed in the version 1.7-0 (available on GitHub). Synthetic data do not have labels though. I hope it is not a big problem.
