read.text is not a common function. I suggest you try read.table, and look at the documentation. Try running ?read.table

thank you

i tried documentation but too confusing for me

data <- read.table("text1", comment.char="#")
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") : cannot open file 'text1': No such file or directory

I suggest that you read this http://www.statmethods.net/input/importingdata.html

This forum is for specific queries of Bioconductor packages and you're having issues with fundamental R commands. You need to be more familiar with R before progressing, try some basic tutorials and get a feel for the environment/ common commands. Also, the documentation of a function or package should be your best friend in these situations.
