Error when running ecocrop() function

[szelepcsenyi]

When all values of minv are 0 in running .doEcocrop() inner function, maxper is also set 0. But this is incorrect because in .ecoSpat() inner function, the e@suitability[0] simply does not exist.
In my opinion, to solve this issue, in the line 215 of the code "ecocrop.R", the value of obj@maxper has to be 1 instead of 0.
