error install package

[lizhongliu1996]

I got this error message below when try to install seq in linux machine:　　　
Error in iconv(x[ind], "latin1", "ASCII", sub = "byte") : 　　　　object 'ind' not found 　　　　　　Execution halted 　　　　Error in run(bin, args = real_cmdargs, stdout_line_callback = real_callback(stdout), : 　　　｀System command error
please modify description file with Encoding: UTF-8 (this can fix the problem).
Also please remove those warnings of no visible binding variable when checking package(this is quite important for passing check on CRAN and BioConductor)
