Incorrect Y-axis scaling in residuals plot

[sbuis]

The Y-axis of the residuals plot is incorrectly scaled, leading to a misleading visualization of the residual distribution. In some cases, residual variability appears compressed or exaggerated, which makes it difficult to properly assess model performance and error structure.

This issue can be reproduced with the following example using the data attached:

vars <- c("chargefruit", "CNgrain", "mafruit")
plot(sim,
     obs = obs,
     type = "scatter",
     select_scat = "res",
     var = vars,
     shape_sit = c("symbol")
)
