FindPeaks {TargetSearch} | R Documentation |
This function extracts the maximum intensity of a list of masses in a given RI window.
FindPeaks(my.files, refLib, columns = NULL, showProgressBar = FALSE)
my.files |
A character vector naming RI files to be searched. |
refLib |
A numeric matrix with three columns or a list of three column matrices. The second column contains the masses and the first and third column contains the RI limits. |
showProgressBar |
Logical. Should the progress bar be displayed? |
columns |
Either |
The reference library parameter refLib
can be either a single
three-column matrix or a list of such matrices. If it is a list, the length
must match the length of my.files
. In this case, every component will
be used to iteratively search in the corresponding file.
The RI files format can be either "text" or "binary". The type is detected dinamically.
A tsMSdata
object.
This is an internal function not intended to be invoked directly.
