mlogit function Error

[Chaagi]

Hi does anyone know how to fix this error in mlogit function?

# a ranked ordered model
data("Game", package = "mlogit")
g <- mlogit(ch ~ own | hours, Game, varying = 1:12, ranked = TRUE,
            reflevel = "PC", idnames = c("chid", "alt"))

Error in is.recursive(.$object) && !is.primitive(.$object) && n > 0 :
'length = 2' in coercion to 'logical(1)'

Try cutting and pasting the below.

library(mlogit)
#> Loading required package: dfidx
#> 
#> Attaching package: 'dfidx'
#> The following object is masked from 'package:stats':
#> 
#>     filter
data("Game", package = "mlogit")
g <- mlogit(ch ~ own | hours, Game, varying = 1:12, ranked = TRUE,
            reflevel = "PC", idnames = c("chid", "alt"))
g
#> 
#> Call:
#> mlogit(formula = ch ~ own | hours, data = Game, reflevel = "PC",     varying = 1:12, ranked = TRUE, idnames = c("chid", "alt"),     method = "nr")
