[R] compare one field of dataframe with excel sheet using R

[sathya7priya]

I have a data frame consisting of three columns(name of compund,ppm and
frequency).Name contains string values .ppm and frequency contains numeric
values with decimal points upto four digits.
I have an excel sheet which is like a library.The first column contains the
name of compounds and remaining column contains the ppm values of the
compound which satisfy certain rules.The number of ppm values varies for
each compound from 4 to 700.
I need to compare the values of ppm from the dataframe and compare it with
the ppm values in excel sheet and give the result if they are similar.
