Importing an Excel file
Hello, R users,
I am a very beginner of R and tried read.csv to import an excel file after
saving an excel file as csv. But it added alternating rows of fictitious NA
values after row number 16. When I applied read.delim, there were trailing
several commas at the end of each row after row number 16 instead of NA

Replies for Importing Excel File
I really appreciate all the helpful answers from Richard Müller, Marc
Schwartz, Adaikalavan Ramasamy, Vito Ricci. I tried Marc's simple suggestion
which was to copy only the data area and paste to a new excel sheet, and
that solved my problem. I'll try other suggestions while I'm learning more
about R. Unedited answers are provided below followed by my question. Thanks
again.

for a nonparametric form of median regression using total variation
of the
derivative of the fitted function as a penalty
