Delete a row in a dataframe and get a dataframe back

Question

I want to "subset" this dataframe and remove the second row using the rowname

myDataFrame <- as.data.frame(rnorm(5))
rownames(MyDataFrame) 
#"1"  "2"  "3"  "4"  "5"  

myDataFrame[-2,]
# 0.2706859  0.9708845  0.7559821 -0.2063368 

I want to be able to get the results above, but in a data frame form (with the original row names). I looked around and it seems the way to select by rowname is to use the which function, but I'm not sure how it would work in this context.

Answer 1

You can add an argument drop = FALSE.

> mydf[-2, , drop = FALSE]
    rnorm(5)
1  1.9602780
3  0.1078827
4 -0.8517422
5 -0.8300695
