This is a bug, thanks for pointing this out.
Fixed for the next release of e1071.

-----------------
Hello,
I would like to read and write sparse matrices using the
functions write.matrix.csr() and read.matrix.csr()
of the package e1071. Writing is OK but reading back the
matrix fails:
x <- rnorm(100)
m <- matrix(x, 10)
m[m < 0.5] <- 0
m.csr <- as.matrix.csr(m)
write.matrix.csr(m, "sparse.dat")
read.matrix("sparse.dat")
Error in initialize(value, ...) : Can't use object of class "integer"
in new(): Class "matrix.csr" does not extend that class
Is something wrong with the code above or it must be
considered as a bug?
Best regards,
Peter
