I am facing an strange error while using SPIA function through ToPASeq package 

> library(ToPASeq)
> expr<-read.csv("gcrma.csv")
> rownames(expr)<-expr$EG
> expr$EG<-NULL
> expr$Symbols<-NULL
> expr<-as.matrix(expr)
> class<-read.csv("disease.csv")
> disease<-class$disease
> names(disease)<-as.vector(class$sample)
> pathways<-pathways("hsapiens", "kegg")[1:10]
> spi<-SPIA(expr, disease, pathways , type="MA", logFC.th=-1)
Error in SPIA(expr, disease, pathways, type = "MA", logFC.th = -1) :
could not find function "SPIA"

my session information is:

Kindly let me know how to rectify it 

AFAIK ToPASeq does not load SPIA, so it seems normal that the function is not available.

library(SPIA)

could do the job?
