Filtering a dataset's columns by another dataset's column names
...me of you can come to my rescue, yet again.
I have two genetic datasets, and I want one of the datasets to have only the columns that are in common with the other dataset.
Here is a toy example (my real datasets have hundreds of columns):
Dataset 1:
Individual SNP1 SNP2 SNP3 SNP4 SNP5
1 A G T C A
2 T C A G T
3 A C T C A
Dataset 2:
Individual SNP1 SNP3 SNP5 SNP6 SNP7
4 A T T G C
5 T A A G G
6 A A T C G
I want Dataset1 to have only columns that are also represented in Datase...

I want these two data frames merged by 'Marker', but when i try
> SNP5 <- merge(SNP4, SNP1, by = 'Marker', all = TRUE)
Error: cannot allocate vector of size 2.4 Gb
In addition: Warning messages:
1: In merge.data.frame(SNP4, SNP1, by = "Marker", all = TRUE) :

permutation and reshuffling
...ber of individuals and creating a loop that will
randomly simulate it for 10000 times *(permutation)*. I also need to find
how I keep the information (p value for each SNP) gathered for all the 10000
iterations.
My data set looks like this (n=500):
Individual #
Phenotype
SNP1
SNP2
SNP3
SNP4
SNP5
SNP6
SNP7
SNP8
SNP9
SNP10
SNP11
