Question

[fatimarasool135]

Hi

I have installed the ballgown package for differential gene expression.

Now I called the library of the installed packages for differential gene expression. but I encountered the following errors (masked) while calling the libraries. Can you tell me how to solve these masked objects from the packages?

the called library as 

library(ballgown)

Attaching package: ‘ballgown’

The following object is masked from ‘package:base’:

    structure

library(RSkittleBrewer)
library(genefilter)
library(dplyr)

Attaching package: ‘dplyr’

The following objects are masked from ‘package:ballgown’:

    contains, expr, last

The following objects are masked from ‘package:stats’:

    filter, lag

The following objects are masked from ‘package:base’:

    intersect, setdiff, setequal, union

library(devtools)

To be safe, you can always specify from which package a function is to be used, e.g. ballgown::expr like package::function

conflicts() is a useful function to see function names that are present in multiple loaded packages, to be implicit which functions we use we can do packageName::functionName(). Relevant SO post:

• What does “The following object is masked from 'package:xxx'” mean?

Those messages are not errors and are completely normal. It just tells you that multiple packages which are loaded on your system use overlapping function names.
