Dear colleagues. I am using RLink for my first time and I am struggling to send a csv data file from Mathematica to R. Having "data" , a csv file in Mathematica, using 

RSet["npldata", data]

in attempt of sending "data" to a dataset "npldata" in R, I receive the following error message: 

RSet::badval: The expression {{row_names,client_idNumber,ApplicationForm_RecordID,EmpiricaScore,Timestamp,BureauRecordID,
AffordabilityRule1,<<38>>,revolving_calc_CurrentMonthsOD_non_nlr,revolving_NumberOfAccounts,revolving_delinquency_new_accounts,
revolving_YearsSinceAccountOpened,instalment_total_commit_nlr,<<10>>},{1,<<49>>,<<10>>},<<47>>,{<<1>>},<<6938>>} is not convertable to R

Please advise. Many thanks in advance,

It is not clear what data you are importing to R. Generally it is nice to test the compatibility of your data using ToRForm function.

From RSet documentation:
"The expression expr must be of the type convertible to R. Normally, you can use the ToRForm function to obtain an internal RLink representation for Wolfram Language expressions you want to send to R, and at the same time test whether or not your expression is legal."
