setwd("microArray/A549_ALI(1)/A549_ALI/4_tert-Butanol (22)/") list.celfiles() my.affy=ReadAffy() my.calls <- mas5calls(my.affy)
This is my code and and up to my.affy it works. Then I get this error message:
my.calls <- mas5calls(my.affy) 'getOption("repos")' replaces Bioconductor standard repositories, see '?repositories' for details replacement repositories: CRAN: https://cran.rstudio.com/ Error in getCdfInfo(object) : Could not obtain CDF environment, problems encountered: Specified environment does not contain miRNA-4_0 Library - package mirna40cdf not installed Bioconductor - mirna40cdf not available
The answers I got here in the forum have unfortunately brought me nothing. I would like to use the mas5calls function.
Thanks for all answers.

As mentioned before, this answer did not help me.
