as.profileCGH {GLAD} | R Documentation |
Create an object of class profileCGH.
as.profileCGH(object,...) ## S3 method for class 'data.frame': as.profileCGH(object, infaction=c("value","empty"), value=20, ...)
object |
A data.frame to be convert into profileCGH. |
infaction |
If "value" then the LogRatio with infinite values
(-Inf, Inf) are replace by + or - value according to the sign. If "empty"
then NAs are put instead. |
value |
replace Inf by value if infaction is
"value". |
... |
The data.frame to be convert must at least contain the
following fields: LogRatio, PosOrder, and Chromosome. If the field
Chromosome is of mode character, it is automatically converted into a
numeric vector (see ChrNumeric
); a field ChromosomeChar
contains the character labels. The data.frame to be converted into a
profileCGH objet is split into two data.frame: profileValuesNA contains
the rows for which there is at least a missing value for either
LogRatio, PosOrder or Chromosome; profileValues contains the remaining rows.
