R help - Apr 2010 - tis: cannot alter subset when input matrix contains NAs

When using the tis time series package (v1.9), I cannot select or alter a subset
of a time series when the time series is created from a matrix and the matrix
contains NA values.

Example:

x<-tis(t(c(1:10,NA)), start=c(2000,1), freq=12)
x[x>0]<-0

The second line yields "Error in if (any(i > nrow(x))) { : missing value
where TRUE/FALSE needed"

However, both of the following work fine:

x<-tis(t(c(1:10)), start=c(2000,1), freq=12) # Does not contain NA
x[x>0]<-0
x<-tis(c(1:10,NA), start=c(2000,1), freq=12) # Contains NA, but input is not
a matrix
x[x>0]<-0

Can someone suggest a solution? Is this a bug? Thanks.

Here is a workaround:

for(i in 1:nrow(x)) x[i, x[i, ] > 0] <- 0
