R help - Aug 2015 - Text Pattern Recognition - Model

Hi,

I have a training dataset which has two columns which has around 70 values.

1.       "PNRNo" whose values like UT768G, CXKA, 4IOI59,
4BV7TW...(typical PNR number patterns)

2.       I have created one more factor variable mentioning (IsPNR) - so all the
values are 1 (true)

My first objective is to create a model on this training set which would
recognize the text pattern.

Second objective: The  model would then be used to predict IsPNR with new set of
test values like "Anshuk", "4EL58S"...as 0 and 1...

Which model would be best for recognizing such kind of pattern and having decent
accuracy? I tried naiveBayes, but I don't think it is all doing a good job.
Its predicting all the test values as true. I suppose bayes is not meant for
this.

Wrong list. This list is about R, not about statistics/statistical
learning. Post to a stats list like stats.stackexchange.com for
methods issues. Once you figure out what you want to do, R almost
certainly can do it -- search to find out what fuctions/packages to
use.

Cheers,
Bert
