Bug during instlling

[9421g]

I use devtools::install_github('mskilab/fragCounter') but 2 bugs ocured.
Error message is missing.
But I changed the source code of ffTrack.R like this:

### for bug1

# setMethod('[', 'ffTrack', function(x, i,
#                                    gr = FALSE, ## if T will return GRanges with field $score populated w values
#                                    raw = FALSE, ## if T will not convert raw data to levels (if levels exist)
#                                    )

setMethod('[', 'ffTrack', function(x, i,
                                   gr = FALSE, ## if T will return GRanges with field $score populated w values
                                   raw = FALSE, ## if T will not convert raw data to levels (if levels exist)
                                   drop = TRUE
                                   )

### for bug2
# setMethod('[<-', 'ffTrack', function(x, i, value, op = NULL, raw = TRUE, full = FALSE)
setMethod('[<-', 'ffTrack', function(x, i, op = NULL, raw = TRUE, full = FALSE, value = NULL)

And I succeeded.
I don't know if this will run properly.
