I have a comma separated string in R:-

\"a,b,c\"

I want to convert it into a list which looks like this:

list(\"a\",\"b\",\"c\"

    This is a basic strsplit problem:

    x <- "a,b,c"
    as.list(strsplit(x, ",")[[1]])
    # [[1]]
    # [1] "a"
    # 
    # [[2]]
    # [1] "b"
    # 
    # [[3]]
    # [1] "c"
    

    strsplit creates a list and the [[1]] selects the first list item (we only have one, in this case). The result at this point is just a regular character vector, but you want it in a list, so you can use as.list to get the form you want.

    With the same logic you can use el:

    as.list(el(strsplit(x, ",")))
    # [[1]]
    # [1] "a"
    # 
    # [[2]]
    # [1] "b"
    # 
    # [[3]]
    # [1] "c"
    

    Or scan:

    as.list(scan(text = x, what = "", sep = ","))
    # Read 3 items
    # [[1]]
    # [1] "a"
    # 
    # [[2]]
    # [1] "b"
    # 
    # [[3]]
    # [1] "c"
