NA erase your data trick

Oops, I just erased all my data using this gizmo that I thought would replace -9 with NA. A) Can I get my tcn5 back?
As you got it the first time. There is nothing like "undo".
B) How do I do it right next time, I learned my lesson, I'll never do it again, I promise!
By vectorization:
tcn5[tcn5 == -9] <- NA

for(i in 1:dim(tcn5)[2]){ ##for the number of columns
+ for(n in 1:dim(tcn5)[1]){ ##for the number of rows
+ tcn5[is.na(tcn5[n,i]) | tcn5[n,i] == -9] <- NA
