Hello Sir/ma'am,

Greetings for the Day !

I am Jyoti Sharma, from India and recently start working on R. I am new in
this field and my knowledge is not up to the mark, so if I sound dumb then
please forgive me.

I tried to read some text file in R so that I can do further analysis on
those files. All files are MicroRNA dataset and in exiqon format. When I
write function ReadExi and path of my file gives me error - Error in a
file(file, "rt") : cannot open the connection.

I put a file in the same directory too, even then also it is not working.
Can you help me on this issue?? Is there any issue with GAL file or
samplesinfo.txt file as these are to be there in same folder as described
in ExiMir package ??

I didn't get this issue. Please help on this matter.

Thanks in advance.

Hi

If you recently start with R maybe you shall spend some time with R intro document to understand R basics.

I looked to ExiMiR package and I must say that although I am after 20 years quite familiar with R I have problems to understand what I should do and I would need to study thoroughly how those files I shall read in look like.

Maybe some people who are familiar with ExiMiR package can give you more insight but in any case you shall provide not only error message but also commands you used before those errors.

My guess is that you did not specify name of the file correctly.

Cheers
Petr
