Anthony, See ?make.names for a description of valid names. Here's an excerpt:
"A syntactically valid name consists of letters, numbers and the dot or underline characters and starts with a letter or the dot not followed by a number. ... The character "X" is prepended if necessary." There is an argument in read.csv() called check.names. Try setting this to FALSE and see if that works. read.csv(file="Something.csv", check.names=F) Jean `·.,, ><(((º> `·.,, ><(((º> `·.,, ><(((º> Jean V. Adams Statistician U.S. Geological Survey Great Lakes Science Center 223 East Steinfest Road Antigo, WI 54409 USA From: Anthony Ching Ho Ng <anthony.ch...@gmail.com> To: r-help@r-project.org Date: 08/10/2011 08:18 AM Subject: [R] column names issue with read.csv Sent by: r-help-boun...@r-project.org Dear List, I wonder why when using read.csv(), if the column name contains a numeric i.e. a stock symbols-"0001.HK", it will automatically insert an "X" character to the column names - "X0001.HK". Now I have to manually do a loop and use substring() to remove the "X" character. Any advice?
