Error when using date time (POSIXct) on the X axis

[GillesSanMartin]

I have a piece of code which was still working 2 months ago and that triggers an error message now (not sure of which updates I made in the meanwhile). This happens when I use POSIXct date-time format for the X axis.

Reproducible example :

df <-
structure(list(Date = structure(c(1680863598, 1680863598, 1680864212, 
1680864212, 1680870200, 1680870200, 1680871367, 1680871367, 1680874534, 
1680874534, 1680880821, 1680880821, 1680882099, 1680882099, 1680891923, 
1680891923, 1680895865, 1680895865, 1680926919, 1680926919, 1680931568
), tzone = "", class = c("POSIXct", "POSIXt")), Language = c("Dutch", 
"French", "Dutch", "French", "Dutch", "French", "Dutch", "French", 
"Dutch", "French", "Dutch", "French", "Dutch", "French", "Dutch", 
"French", "Dutch", "French", "Dutch", "French", "Dutch"), Nb_replies = c(130, 
104, 131, 105, 152, 106, 183, 107, 196, 108, 220, 109, 225, 110, 
235, 110, 246, 111, 248, 112, 252)), row.names = c(NA, -21L), class = "data.frame")

df  

library(echarts4r)
df |> 
    group_by(Language) |>
    e_chart(x = Date) |> 
    e_line(serie = Nb_replies, 
           showSymbol = FALSE,
           type='category') 

Error message received :

Error in cl == "character" || cl == "factor" : 
  'length = 2' in coercion to 'logical(1)'

It works with date format

library(dplyr)
df |> 
    mutate(Date = as.Date(Date)) |> 
    group_by(Language) |>
    e_chart(x = Date) |> 
    e_line(serie = Nb_replies, 
           showSymbol = FALSE,
           type='category')

It's caused by R 4.3.0 changes in if statement (&& and ||), there is a fix on the latest github version of the package

[GillesSanMartin]

Thank you, it works indeed with the latest github version ! Sorry for the inconvenience and thank you for developing and maintaining such a great package !

[JohnCoene]

No worries, thanks for using the package!
