Dear All,

I am a beginner in learning the package of Biostrings currently and for practice doing an example.

 library(Biostrings);
 dnaAlph<-new("BioPatternAlphabet",DNAAlphabet(),c(N="AGCT",
+ B="CGT",D="AGT",H="ACT",K="GT",M="AC",R="AG",S="CG",
+ V="ACG",W="AT",Y="CT"));

Error in getClass(Class, where = topenv(parent.frame())) :

        "BioPatternAlphabet" is not a defined class

I am running R 2.4.1, Wimdows XP, Biostrings_2.2.1 Any help or suggestions that you can provide will be greatly appreciated.

Qing
