Question

Here is my code   x lt -c 1 2  x names x  lt - c  bob   ed   x ed   Why do I get the following error      Error in x ed     operator is invalid for atomic vectors

Because   does not work on atomic vectors  Use   or    instead  From the help file for        The default methods work somewhat differently for atomic vectors  matrices arrays and for recursive  list-like  see is recursive  objects    is only valid for recursive objects  and is only discussed in the section below on recursive objects    x   ed    will work

Here x is a vector  You need to convert it into a dataframe for using   operator      x  lt - as data frame x     will work for you   x lt -c 1 2  names x  lt - c  bob   ed   x  lt - as data frame x    will give you output of x as   bob 1 ed  2  And  will give you output of x ed as  NULL  If you want bob and ed as column names then you need to transpose the dataframe like x  lt - as data frame t x   So your code becomes  x lt -c 1 2  x names x  lt - c  bob   ed   x ed x  lt - as data frame t x     Now the output of x ed is   1  2

You get this error  despite everything being in line  because of a conflict caused by one of the packages that are currently loaded in your R environment   So  to solve this issue  detach all the packages that are not needed from the R environment  For example  when I had the same issue  I did the following   detach package neuralnet    bottom line  detach all the libraries no longer needed for execution    and the problem will be solved

From the help file about    See       you can read        is only valid for recursive objects  and is only discussed in the section below on recursive objects    Now  let s check whether x is recursive   gt  is recursive x   1  FALSE   A recursive object has a list-like structure  A vector is not recursive  it is an atomic object instead  let s check   gt  is atomic x   1  TRUE   Therefore you get an error when applying   to a vector  non-recursive object   use   instead    gt  x  ed   ed   2    You can also use getElement    gt  getElement x   ed    1  2

The reason you are getting this error is that you have a vector      If you want to use the   operator  you simply need to convert it to a data frame  But since you only have one row in this particular case  you would also need to transpose it  otherwise bob and ed will become your row names instead of your column names which is what I think you want   x  lt - c 1  2  x names x   lt - c  bob    ed   x  lt - as data frame t x   x ed  1  2
