I am going to use GOplot package of R to visualize my ontology results out of microarray analysis of cancerous and normal tissues. I have problem with using this code:

circ <- circle_dat(EC$david, EC$genelist)

I have two text files. One for microarray with columns namely: ID, adj.P.Val, logFC. Another file is for david data with columns of: Category, ID, Term, PValue, and Genes. I import these two files into R-studio with these codes:

genelist <- read.csv("genelist.txt", sep = "\t", header = TRUE)
david <- read.csv("BP1.txt", sep = "\t", header = TRUE)

But when I am going to build the circle_dat out of these with this code:

circ <- circle_dat(david, genelist)

I get the error of:

Error in data.frame(category = rep(as.character(terms$category), count),  : 
  arguments imply differing number of rows: 8765, 0

How should I form the circle_dat for my data. By the way, I am just a biologist and does not have any strong background in programming, so please kindly give me a code for this because I cannot understand the programming explanations. I have already saw this link and could not understand anything :( https://stackoverflow.com/questions/29814912/error-replacement-has-x-rows-data-has-y Thank you.
