replaceVectorByEquality

A vector to be replaced. The items of the vector must be
  atom types, since the equality is checked by '=='.

vector

targets to be replaced, could be either single or a
    vector

target

values to be replaced at the positions of targets, must
    be of the same length of <code>target</code>

value


  The function replces (or updates) the items of a given vector by
  checking the equality with the <code>target</code> parameter. If found, the
  item will be replaced by the <code>value</code> parameter. The length of
  both <code>target</code> and <code>value</code> must be the same and could be
  longer than 1, in which case the replace will be iterated.


The Delta-Delta-Ct (ddCt) Algorithm is an approximation method to determine relative gene expression with quantitative real-time PCR (qRT-PCR) experiments. Compared to other approaches, it requires no standard curve for each primer-target pair, therefore reducing the working load and yet returning accurate enough results as long as the assumptions of the amplification efficiency hold. The ddCt package implements a pipeline to collect, analyse and visualize qRT-PCR results, for example those from TaqMan SDM software, mainly using the ddCt method. The pipeline can be either invoked by a script in command-line or through the API consisting of S4-Classes, methods and functions.
