R help - Jul 2005 - delete a row from a matrix

Hi,
I would like to know if it's possible to delete a rox from a matrix?
 
> fig
     [,1] [,2] [,3] [,4]
[1,]    0    1  0.0  0.2
[2,]    0    1  0.2  0.8
[3,]    0    1  0.8  1.0
[4,]    0    1   NA   NA
[5,]    0    1   NA   NA

I would like to delete the 2 rows with NA!

Thanks
 
Sabine

fig <- fig[-c(4,5),]

or, more generally

fig <- fig[complete.cases(fig),] 

or, even more generally

fig <- fig[!apply(is.na(fig), 1, any),]
