correlation output misses one of the algorithms in the ensemble

[AMBarbosa]

Hi,
The Example in the ?ensemble_modelling help file runs two algorithms, but the output correlation between algorithms is empty. If I add more algorithms, the output correlation misses the first one:

ESDM <- ensemble_modelling(c('MARS', 'CTA', "GLM"), Occurrences, Env, rep = 1,
                           Xcol = 'LONGITUDE', Ycol = 'LATITUDE',
                           ensemble.thresh = c(0.6))

plot(ESDM)

#                  CTA.SDM.ensemble GLM.SDM.ensemble
# CTA.SDM.ensemble        1.0000000        0.2152712
# GLM.SDM.ensemble        0.2152712        1.0000000

Regards,

The algorithm evaluation output (including in the plot(ESDM) graphical window) also misses one of the algorithms:

ESDM <- ensemble_modelling(c('CTA', 'MARS'), Occurrences, Env, rep = 1,
                           Xcol = 'LONGITUDE', Ycol = 'LATITUDE',
                           ensemble.thresh = c(0.6))

Thanks @AMBarbosa , weirdly I cant reproduce the bug myself:

GLM.SDM.ensemble          0.7317545        0.4394027        1.0000000

Could you give me more information on your environment?
