I have a dataframe like x where the column genes is a factor. I want to remove all the rows where column genes has nothing. So in table X I want to remove row 4. Is there a way to do this for a large dataframe? 

X 
names   values   genes
1 A  0.2876113  EEF1A1 
2 B  0.6681894   GAPDH
3 C  0.1375420 SLC35E2
4 D -1.9063386        
5 E -0.4949905   RPS28

Finally result:

X 
names   values   genes
1 A  0.2876113  EEF1A1 
2 B  0.6681894   GAPDH
3 C  0.1375420 SLC35E2
5 E -0.4949905   RPS28

Thank you all!

    It’s not completely obvious from your question what the empty values are, but you should be able to adopt the solution below (here I assume the ’empty’ values are empty strings):

    toBeRemoved<-which(X$genes=="")
X<-X[-toBeRemoved,]
