Dear R helpers,
Please have a look at the following : -
Note : My goal is to find and replace all Inf's in a data array with 0.
> t<-data.frame(A=c(Inf,0,0),B=c(1,2,3))
> t
A B
1 Inf 1
2 0 2
3 0 3
>str(t)
'data.frame': 3 obs. of 2 variables:
$ A: num Inf 0 0
$ B: num 1 2 3
> t[which(t==Inf,arr.ind=T)]
[1] Inf
> t[which(t==Inf,arr.ind=T)]<-0
Error in `[<-.data.frame`(`*tmp*`, which(t == Inf, arr.ind = T), value = 0)
:
only logical matrix subscripts are allowed in replacement
Query : Why does the search work but the replace not work ?
Many thanks for your time and efforts.
