I downloaded dataset and column names from website https://archive.ics.uci.edu/ml/machine-learning-databases/breast-cancer/ breast-cancer.data - Has Data without column header breast-cancer.names - Has Column names I need to load this data and column names to R and then need to attach the column names to the data frame. Please guide me the whole procedure to do it.
The .data file is merely a CSV without columns headers. The .names file is not in a standard format (that I recognize), so I read the file and assigned names manually.
dat <- read.csv("~/Downloads/breast-cancer.data", header=FALSE)
names(dat) <- c("class", "age", "menopause", "tumor_size", "inv_nodes", "node_caps", "deg_malig", "breast", "breast_quad", "irradiat")
head(dat)
