I've used the spread
function in tidyverse before, and it worked fine. Now, however, it raises this error message for all uses of the spread function:
df <- data_frame(x = c('a', 'b'), y = 1:2)
df %>% spread(x, y)
Error in synthetic.instrument(primary_id = primary_id, currency = currency, : object 'y' not found
Error in synthetic.instrument(primary_id = primary_id, currency = currency, : argument "memberratio" is missing, with no default
What is causing the error?
