# Hi there. # I'm not sure whether or not this is a bug. # But it surely is an unexpected behaviour. V <- seq(from=0,to=1,by=0.1) # Should generate a sequence with a step of 0.1 V==0 # [1] TRUE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE # Ok! V==0.1 # [1] FALSE TRUE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE # Ok! V==0.6 # [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE # None? V[7] # [1] 0.6 V[7]==0.6 # [1] FALSE # Rounding!? V[8] # [1] 0.7 V[8]==0.7 # [1] FALSE # Rounding!? V[9] # [1] 0.8 V[9]==0.8 # [1] TRUE # Back to normal # The generated sequence is fine for all values except for 0.6 # and 0.7, which appear to be somewhat off the expected value. # According to the R manual the sequence is generated in the form: # from, from+by, ..., to # which is not the case. # Either the function or the documentation lead to an unexpected # behaviour of seq(from,to,by). # Thanks! ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
