[R] how to merge 5 data frames by one column

[Ana Marija]

Hello,

I have 5 dataframes (s11,s22,s33,s44,s55) that look like this:

> head(s11)
               V1.1                          rs         V3.1        V4.1
1 ENSG00000154803  rs12940868 3.80175e-05 -0.519565
2 ENSG00000154803   rs4383187 8.92772e-05 -0.367303
3 ENSG00000154803   rs4404112 9.32402e-05 -0.366634
4 ENSG00000154803   rs7214091 8.38003e-05  0.337576
5 ENSG00000154803  rs35871790 9.67028e-05 -0.305755
6 ENSG00000154803 rs112532541 1.08341e-04 -0.305493

> head(s22)
               V1.2                               rs        V3.2      V4.2
602 ENSG00000264589  rs62065452 1.34475e-17 -0.695948
603 ENSG00000264589 rs377004743 1.26272e-17 -0.695627
630 ENSG00000264589   rs1724390 1.01129e-17 -0.693518
643 ENSG00000264589 rs367637729 4.05726e-17 -0.682833
653 ENSG00000264589 rs376183404 1.13177e-17 -0.697646
673 ENSG00000264589 rs112327620 1.59840e-17 -0.707904

Each one has one unique value in respective V1

I am trying to merge all at once all 5 data frames by the "rs" column.

Can you please help with this,
Ana
