  • could not find function "readCufflinks" cummeRbund

    Hi,
    I have used cummeRbund a bit recently with Cuffdiff outputs from runs on Galaxy. It has worked ok but the last few days it does not. I have tried to install the package again but no success. Please see below for my problems, the function "readCufflilnks" does not work, anyone know why? Many thanks!

    Cuffdiff v 0.0.5
    R studio v 0.97.449
    R 2.15.3

    I have to warn you I am pretty new to R, but I was lucky that mine was workingbut could it be the space between readCufflinks and the parenthesis? readCufflinks(...)

    can you try it without the space and see if it works?

      yeah, its not the space. sorry.

        I guess the package is not intalled correctly for some reason, but I do not know why.. It has worked on the same computer until recently.

          Hi

          I have a similar problem.

          Error in loadNamespace(i, c(lib.loc, .libPaths())) :
          there is no package called ‘colorspace’
          Error: package ‘ggplot2’ could not be loaded

          Error: could not find function "readCufflinks"[/QUOTE]

          This means that ‘ggplot2’ are not installed and cummeRbund needs ggplots
          to work.

          So you should install 'ggplot2' beforehand as follows.

          >install.packages("ggplot2", dependencies=TRUE)

            Try this

            library(cummeRbund)

              Current Approaches to Protein Sequencing
              by seqadmin


              Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

              Strategies for Sequencing Challenging Samples
              by seqadmin


              Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
