matrices must have every element be the same class Data frames also have a special attribute called row.names Data frames are usually created by calling read.table() or read.csv() Can be converted to a matrix by calling data.matrix() > x <- data.frame(foo = 1:4, bar = c(T, T,...
6. Raw Data Type Arawdata type specifies values as raw bytes. You can use the following methods to convert character data types to a raw data type and vice-versa: charToRaw()- converts character data to raw data rawToChar()- converts raw data to character data For example, # convert...
