I am trying to plot heatmap for some selected genes using cummeRbund R package. I was trying create a gene set using command:

myGenesIDs <- c("Vradi01g04230", "Vradi01g07000", "Vradi01g12360", "Vradi01g12370", "Vradi02g12120", "Vradi10g10130")
myGenes<-getGenes(cuff_data, myGenesIDs)

but i am getting this error

**Getting gene information:
    FPKM
Error: near ")": syntax error
In addition: Warning message:
Closing open result set, pending rows**

and

Error: cannot start a transaction within a transaction

how to solve it
