Question on Import

Hi!

I have the data in a tab delimited text file titled "ken_data_try_anova." I 
tried to import it into R entering

read.delim(ken_data_try_anova)

but received the error message

Error in read.table(file = file, header = header, sep = sep, quote = quote,  : 
  object 'ken_data_try_anova' not found

I have another file called 10423nad.txt.

I tried

data<-as.matrix(read.table(C:\Users\gtsalazar1979\Documents\TANOVA_1.0.0\10423nad.txt))
)

but got the error message
Error: unexpected input in "data<-as.matrix(read.table(C:\"

How do I place the data where the import function can find it? Or, how do I 
correct my use of the import functions?

Thank you for your time and patience! Any guidance toward a solution means a lot 
to me :)
Cheers,
