I am trying the following code...
for(i in 1:bins){
print(cat(c(i, length(var1[var1==i]))))
}
Where var1 is a vector with zero or more values = {1, 2, ..., bins} (or
something like that).
The result I get is...
1 33NULL
2 28NULL
3 39NULL
4 27NULL
5 32NULL
6 30NULL
7 23NULL
8 16NULL
9 10NULL
10 15NULL
11 13NULL
12 7NULL
13 3NULL
14 7NULL
15 2NULL
16 0NULL
17 2NULL
18 0NULL
19 0NULL
20 3NULL
I don't know what I am doing to get those stray NULL characters printed.
I also tried...
for(i in 1:bins){
print(cat(i, length(var1[var1==i])))
}
Which is essentially the same.
