inverse.transform {CatEncoders} | R Documentation |
inverse.transform transforms an integer vector back to the original vector
Description
inverse.transform transforms an integer vector back to the original vector
Usage
inverse.transform(enc, z)
## S4 method for signature 'LabelEncoder,numeric'
inverse.transform(enc, z)
Arguments
enc |
A fitted LabelEncoder |
z |
A vector of integers |
Value
A vector of characters, factors or numerics.
Examples
# character vector y
y <- c('a','d','e',NA)
lenc <- LabelEncoder.fit(y)
# new values are transformed to NA
z <- transform(lenc,c('d','d',NA,'f'))
print(z)
inverse.transform(lenc,z)
# factor vector y
y <- factor(c('a','d','e',NA),exclude=NULL)
lenc <- LabelEncoder.fit(y)
# new values are transformed to NA
z <- transform(lenc,factor(c('a','d',NA,'f')))
inverse.transform(lenc,z)
# numeric vector y
set.seed(123)
y <- c(1:10,NA)
lenc <- LabelEncoder.fit(y)
# new values are transformed to NA
newy <- sample(c(1:10,NA),5)
print(newy)
z <-transform(lenc,newy)
inverse.transform(lenc, z)
