Dateline crossing #117

Open JoChambon opened 1 year ago

JoChambon commented 1 year ago

Hi,

There seems to still be issues with the dateline crossing. I tried to animate the track from one animal that crosses the dateline but received a warning message that the argument 'cross_dateline' was ignored due to CRS specification, but as far as I am aware of the CRS I specified is unprojected/geographical.

move_data <- df2move(df=data_sub_2,proj="+proj=longlat +datum=WGS84",x="lon",y="lat",time="timestamp") #track from only one animal
m <- align_move(move_data, res = 15, unit = "mins") #tracking resolution of 15mins
frames <- frames_spatial(m, cross_dateline = TRUE) #track crossing the dateline

Warning: Argument 'cross_dateline' is ignored, since the coordinate reference system of 'm' is not geographical (long/lat).

Error in .local(x, values, ...) : the size of 'values' is not correct

Any idea where the issue might come from?

Reinstalling the package from github with devtools rather than install.packages() solved this issue. devtools::install_github("16EAGLE/moveVis")
