Help with BIOMOD_FormatingData - [The function cannot form a database of species information and environmental information]

[liushuhao-666]

Hi,

I'm using my own species information, including 0/1 and latitude and longitude, as well as environmental grids. I made sure that the species information was not duplicated and that the grid was fine. When I use the BIOMOD_FormatingData function, it doesn't work. See the result below.

I find this function does not work, I do not know why, please teach me how to solve it.

myExpl class : SpatRaster dimensions : 18, 15, 5 (nrow, ncol, nlyr) resolution : 0.5, 0.5 (x, y) extent : 119.75, 127.25, 26.25, 35.25 (xmin, xmax, ymin, ymax) coord. ref. : lon/lat WGS 84 (EPSG:4326) sources : bs_mean.img
bt_mean.img
depth_mean.img
... and 2 more source(s) names : bs, bt, depth, sss, sst min values : 30.2822, 9.984425, 16.00, 17.90484, 13.92985 max values : 34.8130, 25.676500, 138.25, 34.37285, 27.58349

plot(myBiomodData) 错误于.plot.BIOMOD.formated.data.check.args(x = x, calib.lines = calib.lines, : coordinates are required to plot BIOMOD.formated.data objects

Hello Mingmou,

Thank you for posting :pray:

That is strange indeed, as you both have no presences kept within your BIOMOD.formated.data object, nor values within your explanatory variables 👀

Could you please send the output of the sessionInfo() command ? Also, in order to check that both your explanatory variables and occurrence data are in the same projection system, could you try and plot them together ?

## For example with : 
plot(myExpl[[1]])
points(myRespXY, add = TRUE)

## But it might depend on the format of your object
