Error while reading csv file in R

Question

I am having some problems in reading a csv file with R.

 x=read.csv(\"LorenzoFerrone.csv\",header=T)

Error in make.names(col.names, unique = TRUE) : 
      inva         


        

Answer 1

You can always use the "Latin1" encoding while reading the csv:

 x = read.csv("LorenzoFerrone.csv", fileEncoding = "Latin1", check.names = F)

I am adding check.names = F to avoid replacing spaces by dots within your header.

Answer 2

This will read the column names as-is and won't return any errors:

x = read.csv(check.names = F)

To remove/replace troublesome characters in column names, use this:

iconv(names(x), to = "ASCII", sub = "")

Answer 3

Not sure if this is helpful, but I had a similar problem and figured out that it was because my "csv" file had a .csv suffix, but was actually a .xls file!

Answer 4

I solved the problem by removing any graphical signs in the writing (i.e. accent marks). My headers were written in Spanish and had some accent marks in there. I replaced with simple words (México=Mexico) and problem was solved.

Answer 5

Change the file format to - CSV UTF-8. It worked for me.
