data(simdat)
# Model for illustrating coefficients:
m0 <- bam(Y ~ s(Time) + s(Subject, bs='re') 
+ s(Time, Subject, bs='re'), data=simdat)

# get all coefficients:
coef(m0)
# to get only the Subject intercepts:
coef(m0)[grepl(convertNonAlphanumeric('s(Subject)'), names(coef(m0)))]
# to get only the Subject slopes:
coef(m0)[grepl(convertNonAlphanumeric('s(Time,Subject)'), names(coef(m0)))]
