Hello,
I am trying to do a spearman correlation. My data has tied values. To
overcome this issue, I am adding some random noise (values) to my original
data. However when I add the random noise to the data, the final matrix does
not show the new values. I guess the reason being that the noise I add is
very small and the full value including the decimals gets truncated to show
only the value upto two decimal points. Is there a way to keep the full value
as it is without truncation. Thanks for your suggestions in advance.
My script:
rand.val: stores the random numbers
data: stores the actual values
rand.val<-data.frame(a=runif(11,0.000000001,0.00000001),b=runif(11,0.00000000
1,0.00000001),
c=runif(11,0.000000001,0.00000001),d=runif(11,0.000000001,0.00000001),e=runif
(11,0.000000001,0.00000001),f=runif(11,0.000000001,0.00000001),g=runif(11,0.0
00000001,0.00000001),h=runif(11,0.000000001,0.00000001))
rand.val<- as.matrix(rand.val)
