Yes it does have something to do with the representation of floating point
numbers.

Hello,

[1] TRUE
So I guess it does have to do with floating-point equality, all.equal
uses .Machine$double.eps. (Which could return FALSE on ocasions we would
expect TRUE, when, for instance, the tolerance could/should be
.Machine$double.eps^0.5.)

HI R help,
I was trying to get identical data frame from a list using two methods.
#Suppose my list is:
listdat1<-list(rnorm(10,20),rep(LETTERS[1:2],5),rep(1:5,2))
#Creating dataframe using cbind
dat1<-data.frame(do.call("cbind",listdat1))
colnames(dat1)<-c("Var1","Var2","Var3")
#Second datafram
6 matches
