getValuesByUnique: Print matrix-content as plot

Description

When data have repeated elements (defined by names inside the vector), it may be advantageous to run some operations only on a unique set of the initial data, or somtimes all repeated occurances need to be replaced by a common (summarizing) value. This function allows to re-introduce new values from on second vector with unique names, to return a final vector of initial input-length and order of names (elements) like initial, too. Normally the user would provide 'datUniq' (without repeated names) containing new values which will be expanded to structure of 'dat', if 'datUniq' is not provided a vector with unique names will be made using the first occurance of repeated value(s). For more complex cases the indexing relative to 'datUniq' can be returned (setting asIndex=TRUE). Note: If not all names of 'dat' are found in 'datUniq' the missing spots will be returned as NA.

Usage

getValuesByUnique(
  dat,
  datUniq = NULL,
  asIndex = FALSE,
  silent = FALSE,
  callFrom = NULL
)

Arguments

dat

(numeric or character) main long input, must have names

datUniq

(numeric or character) will be used to impose values on dat, must have names that should match names (at least partially) from dat

asIndex

(logical) if TRUE index values will be returned instead of replacing values

silent

(logical) suppress messages

callFrom

(character) allow easier tracking of message(s) produced

Value

vector of length dat with imposed values, or index values if asIndex=TRUE

Examples

# NOT RUN {
dat <- 11:19
names(dat) <- letters[c(6:3,2:4,8,3)]
## let's make a 'datUniq' with the mean of repeated values :
datUniq <- round(tapply(dat,names(dat),mean),1)
## now propagate the mean values to the full vector
getValuesByUnique(dat,datUniq)
cbind(ini=dat,firstOfRep=getValuesByUnique(dat,datUniq),
  indexUniq=getValuesByUnique(dat,datUniq,asIn=TRUE))
# }
