Some comma-delimited files will have data values enclosed in quotes to avoid problems where data values include commas. The dsd option deals with this too, by ignoring commas within quotes and removing the quotes from the data values. The missover option is also recommended for CSV files to prevent SAS going to a new line where the last value on a data line is missing. There is an example in Chapter 14. CSV files may also contain the names of the variables as the first line of the file. To skip this line when reading the data, use the firstobs ¼ 2 option.
2: sgplot, sgpanel, sgmatrix and sgrender. ) The new procedures, particularly sgplot, can produce a wide range of attractive graphs relatively simply, and for many users, it will be all they need. To avoid repetition we will concentrate on the new procedures in the text, but will illustrate alternatives using the traditional procedures in the downloadable source code. 1 xy Plots – Proc sgplot An xy plot is one in which the data are represented in two dimensions defined by the values of two variables.
The first form begins with an asterisk and ends with a semicolon, for example, * this is a comment; The second form begins with =* and ends with *=. =* this is also a comment *= Comments may appear on the same line as a SAS statement, for example, bmi ¼ weight=height**2; =* Body Mass Index *= The enhanced editor colour codes comments green, so it is easier to see if the *= has been omitted from the end or if the semicolon has been omitted in the first form of comment. The first form of comment is useful for ‘‘commenting out’’ individual statements, whereas the second is useful for commenting out one or more steps since it can include semicolons.
