I have 33 co

You can use paste0 command

    > c(paste0("f", 1:32), "label")


     [1] "f1"    "f2"    "f3"    "f4"    "f5"    "f6"    "f7"    "f8"    "f9"    "f10"   "f11"   "f12"  
    [13] "f13"   "f14"   "f15"   "f16"   "f17"   "f18"   "f19"   "f20"   "f21"   "f22"   "f23"   "f24"  
    [25] "f25"   "f26"   "f27"   "f28"   "f29"   "f30"   "f31"   "f32"   "label"

This will do the job

colnames(urc_training_norm) <- c(paste0("f", 1:32), "label")
