[Solved] Convert categorical column to multiple binary columns [duplicate]

One way could be using unique with a for-loop 

Breed = c(
  "Sheetland Sheepdog Mix",
  "Pit Bull Mix",
  "Lhasa Aposo/Miniature",
  "Cairn Terrier/Chihuahua Mix",
  "American Pitbull",
  "Cairn Terrier",
  "Pit Bull Mix"
)
df=data.frame(Breed)

for (i in unique(df$breed)){
  df[,paste0(i)]=ifelse(df$Breed==i,1,0)
}
