add variable in glob2rx function in r
0
I want to get an expression and then put it in the glob2rx function, like:
glob2rx("*A*cfs*")
glob2rx("*B*cfs*")
glob2rx("*C*cfs*")
glob2rx("*D*cfs*")
because I want to use this expression to list file in folder, like:
list.files(pattern=glob2rx("*A*cfs*"))
I want to add a vector like:(looping through df)
df <- c("A","B","C","D")
ef <- paste0(""","*",df[i],"*","cfs","*")
list.files(pattern=glob2rx(ef))
But It did not work.
Could you give me some hints?

You're not closing with a ". When you're looping, you can use
path <- getwd()
df <- c("A","B","C","D")
for(i in 1:length(df)){
ef <- paste0("*",df[i],"*","cfs","*")
list.files(path=path,glob2rx(pattern=ef))
}
