names attribute must be the same length as the vector

Question

Stuck on an error in R        Error in names x   lt - value           names  attribute must be the same length as the vector   What does this error mean

User · Answer

I encountered the same error for a silly reason, which I think was this:

Working in R Studio, if you try to assign a new object to an existing name, and you currently have an object with the existing name open with View(), it throws this error.

Close the object 'View' panel, and then it works.

I have seen such error and i solved it  You may have missing values in your data set  Number of observations in every column must also be the same

The mistake I made that coerced this error was attempting to rename a column in a loop that I was no longer selecting in my SQL  This could also be caused by trying to do the same thing in a column that you were planning to select  Make sure the column that you are trying to change actually exists

I want to explain the error with an example below    gt  names lenses   1   X1  1  1  1  1  3       names lenses  c  ID   Age   Sight   Astigmatism   Tear   Class     Error in names lenses    c  ID    Age    Sight    Astigmatism    Tear            names  attribute  6  must be the same length as the vector  1    The error happened because of mismatch in a number of attributes  I only have one but trying to add 6 names  In this case  the error happens  See below the correct one            gt  names lenses  c  ID    gt  names lenses        1   ID    Now there was no error   I hope this will help

For me  this error was because I had some of my data titles were two names  I merged them in one name and all went well

In the spirit of  Chris W  just try to replicate the exact error you are getting  An example would have helped but maybe you re doing          x  lt - c 1 2    y  lt - c  a   b   c     names x   lt - y  Error in names x   lt - y       names  attribute  3  must be the same length as the vector  2    I suspect you re trying to give names to a vector  x   that is shorter than your vector of names  y

Depending on what you re doing in the loop  the fact that the  in  operator returns a vector might be an issue  consider a simple example   c1  lt - c  one   two   three   more   more   c2  lt - c  seven   five   three    if c1 in c2        print  hello       then the following warning is issued   Warning message  In if  c1  in  c2        the condition has length  gt  1 and only the first element will be used   if something in your if statement is dependent on a specific number of elements  and they don t match  then it is possible to obtain the error you see
