R help - Nov 2016 - How to extract parameters from train in caret package

Dear R-users,
   I need to extract coefficients  from the  final model after running
train function of caret package.

I need to have something like "summary" used after running a
regression
model
in this case  from the best model.

below my  script   as explanation

data(Sonar)
set.seed(107)
 inTrain <- createDataPartition(y = Sonar$Class,  p = .75,  list = FALSE)

training <- Sonar[ inTrain,]
testing <- Sonar[-inTrain,]


 plsFit <- train(Class ~ .,
                   data = training,
                  method = "pls",
                  tuneLength = 15,
                  preProc = c("center", "scale"))

What I need is a summary  which looks like


Call:
glm(formula = Class ~ ., family = "binomial", data = training)

Deviance Residuals:
       Min          1Q      Median          3Q         Max
-2.418e-05  -2.110e-08  -2.110e-08   2.110e-08   2.697e-05

V13          1.746e+02  1.246e+06   0.000    1.000


    Null deviance: 2.1688e+02  on 156  degrees of freedom
Residual deviance: 1.0630e-08  on  96  degrees of freedom
AIC: 122
