Is it possible to change the column names of the dataset that I m using in R

Question

I have a dataset that I'm using for analysis. The problem is, it has very long column names and I would like to change them. Is that possible in R

Answer 1

That is definitely possible in R. You can use the package plyr for this purpose. 

plyr is a set of tools for a common set of problems: you need to split up a big data structure into homogeneous pieces, apply a function to each piece and then combine all the results back together. For example, you might want to:

• fit the same model each patient subsets of a data frame
• quickly calculate summary statistics for each group
• perform group-wise transformations like scaling or standardising

my_data1 <- plyr::(my_data1, c("old-column-name1"="New-column-name1",
                                                   "old-column-name2"="new-column-name2",
                                                    .........................................))

Hope this was helpful :)
