If arrays are combined using c it strips the dim and dimnames attributes which are required by ftable. txt file opens in Notepad. csv file opens in MS Excel. 11 See: help(Sweave). 2 Graphs The original R graphics package is referred to as ‘‘base graphics’’. Other graphics packages include lattice and ggplot2. 1 Base Graphics The concept of the base graphics functions is for successive functions to add graphics and build plots up.

Matrix and data frame cells have pairs of indices, respectively for rows and columns, as in: x[i,j]. Arrays have tuples of indices depending on the dimensionality of the array, as in: x[i,j,k] 30 2 Data Structures (for a 3-dimensional array). An empty index is shorthand for a complete index. For example: [ swiss½cð10; 15Þ; 2:3Š [ swiss½cð10; 15Þ; Š [ swiss½; 2:3Š # Index rows 10 and 15; and columns 2 to 3 # Rows 10; 15 and all columns ðempty column indexÞ # Columns 2:3 and all rows ðempty row indexÞ If the object has named parts an index vector can be character or numeric: [ swiss½cð10; 15Þ; cð"Agriculture"; "Examination"ފ # Same as: swiss½cð10; 15Þ; 2:3Š A single index to a data frame accesses columns by number or by name.
