Hi,
I have a file in .sas7bdat format. I tried to open this file using
read.sas7bdat() function.
This gave me an error - "Error in read.sas7bdat("bnp_genetic.sas7bdat") :
unknown host X64_7PRO".
Could someone tell me what this error means?
Thank you,

Hi,
Is there a command to get the indices of intersecting elements of two
vectors as intersect() will give the elements and not its indices.
Thanks in advance.

Hi all,
Is there a way to get the index of elements in intersect(x,y) where x and y
are vectors with few common elements.
Appreciate your response.

Hi,
Is there a function in R to do a-b where a and b are two non-numeric sets
(or intersection complement of these two sets).
Kind Regards,
