Remove NA/NaN/Inf in a matrix

Question

I want to try two things :

1. How do I remove rows that contain NA/NaN/Inf
2. How do I set value of data point from NA/NaN/Inf to 0.

So far

Answer 1

NaRV.omit(x) is my preferred option for question 1. Mnemonic NaRV means "not a regular value".

require(IDPmisc)
m <- matrix(c(1,2,3,NA,5, NaN, 7, 8, 9, Inf, 11, 12, -Inf, 14, 15), 5)
> m
     [,1] [,2] [,3]
[1,]    1  NaN   11
[2,]    2    7   12
[3,]    3    8 -Inf
[4,]   NA    9   14
[5,]    5  Inf   15
> NaRV.omit(m)
     [,1] [,2] [,3]
[1,]    2    7   12
attr(,"na.action")
[1] 1 3 4 5
attr(,"class")
[1] "omit"
