convert numeric values to logicals

Through The SQL: Boolean Field in Visual Foxpro and MS

In Visual Foxpro 9 (VFP) and it's lower versions there exists a logical field with which a programmer can use to have some kind of a digital flip-type switch that we regularly use in queries or in a control like a checkbox for example If one can imagine how a light switch works the idea behind is the same with that of a logical field The apparent difference emerging from that point

Expressions: SAS Operators in Expressions

Comparison operators set up a comparison operation or calculation with two variables constants or expressions If the comparison is true the result is 1 If the comparison is false the result is 0 Comparison operators can be expressed as symbols or with their mnemonic equivalents which are shown in the following table:

Chapter 2 Data Frames

Numeric - These could be any number (whole number or decimal) To convert another type to numeric you may use the function as numeric() Strings - These are a collection of characters (example: Storing a student's last name) To convert another type to a string use as character() Factors - These are strings that can only values from a

Working with categorical data

Working with categorical data {ch:working} In R a vector is a collection of values like numbers character strings logicals (TRUE FALSE) or dates and often correspond to a variable in some analysis Matrices are rectangular arrays like a traditional table composed of vectors in their columns or rows Arrays add additional dimensions so that for example a 3-way table can be

Its value is either a vector a logicals or a vector of numeric or character indices to specify which columns should not be converted to factors The argument will be replicated as needed to be of length equal to the number of fields thus as is=FALSE converts all character fields na strings character vector these characters will be interpreted as NA values Blank fields are also considered

Dataframes

Its value is either a vector of logicals (values are recycled if necessary) or a vector of numeric or character indices which specify which columns should not be converted to factors Note: to suppress all conversions including those of numeric columns set colClasses = character Note that as is is specified per column (not per variable) and so includes the column of row names (if any) and

Basic Data Types

Learning objectives We have seen that we can store objects in the R workspace In our earlier example we created variables that would store one piece of information i e a number As you would expect R can in fact store different types of data We call them the basic R data types We call them "basic" because they can assembled into more complex data structures (vectors arrays

How to Compare Values in Logical Vectors in R

To build logical vectors in R you'd better know how to compare values and R contains a set of operators that you can use for this purpose Operator Result x == y Returns TRUE if x exactly equals y x != y Returns TRUE if x differs from y x y Returns TRUE if []

Chapter 8:

We will compare numeric values with predicates like E1 E2 and E1 = E2 These extensions mean that expressible values are atoms ints and data structures constructed by functors Recall from the previous chapter that the data type of trees can be defined with a leaf data structure and a node data structure A tree data structure is either a leaf of a node node(E T1 T2) where E is an

the default behavior of read table is to convert character variables (which are not converted to logical numeric or complex) to factors The variable as is controls the conversion of columns not otherwise specified by colClasses Its value is either a vector of logicals (values are recycled if necessary) or a vector of numeric or character indices which specify which columns should not be

Using logical operators and conditional statements

In this lab you will practice using conditional statements Use a mask to find all the entries in the vector x that are between -0 5 and 0 5 x = -1 + 2*rand(10 1) Use the Matlab find function to find the index of the first three entries in the array x x = -10 + 20*rand(100 1)
