it's mi first question Im having trouble when comparing an array, colum value, etc with number 0.7 in R I've found some questions which includes this value, but not related to this apparet "bug"
As example
f<-(1:9)*0.1
f==0.8
#[1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE TRUE FALSE
#or
which(f==0.8)
#[1] 8
#as expected, but when it's 0.7
f==0.7
#[1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE
which(f==0.7)
#integer(0)
Although it can be 'solved' quoting the value ...
which(f=='0.7')
#[1] 7
may it be a bug?
