I need to left join results of table to generated sequence. Because it did not work as expected (some rows were missing), I tried to compare values in both variables. Why some values of df$c are not equal to values generated using seq()?
# Sample data
a <- runif(100)
b <- runif(100) > .5
step <- .1
# This is what I do in my real task
df <- as.data.frame.matrix(table(trunc(a / step) * step, b))
df$c <- as.numeric(rownames(df))
# Would like to join, but comparsion of df$c and generated sequence
# return FALSE for some elements.
df$c == seq(0, 0.9, step)
# Returns> [1] TRUE TRUE TRUE FALSE TRUE TRUE FALSE FALSE TRUE TRUE
