In Example 2, I’ll illustrate how to use the functions of the dplyr package to round each numeric variable of our data frame.In order to use the functions of the dplyr package, we first need to install and load dplyr:install.packages("dplyr") # Install & load dplyr package library("...
R语言因子factor数据类型:使用factor函数将字符串向量转化为因子向量、使用ordered函数将字符串向量转化为有序的因子向量(ordinal categorical variable) R语言数据类型(data types) R语言因子(factor)数据类型、factor函数将字符串向量因子化(标称变量)、使用ordered函数基于levels参数对因子变量进行自定义排序称为序数因子...
This section illustrates how to convert a discrete factor variable to a continuous data object in R.For this task, we have to apply the as.numeric and as.character functions as shown below:x_cont <- as.numeric(as.character(x)) # Convert factor to numeric x_cont # Print numeric variable...
It is important that R knows whether it is dealing with a continuous or a categorical variable, as the statistical models you will develop in the future treat both types differently. (You will see later why this is the case.) A good example of a categorical variable is the variable 'Gende...
Dear Statausers, When I run this command: tsset dtt probit y l.x1 l.x2 mfx I get the following error: factor variables and time-series operators not allowed r(101); What could be the reason for no mfx for lagged variables in time-series? Or am I missing something? Any comments woul...
We need to make it a numeric variable in some way. That's where dummy coding comes in. Two levels Example with gender which has two levels (male or female) We create a new variable <MATH> X = \left\{\begin{array}{ll} 1 & \text{ if the person is a male} \\ 0 & \text...

In Example 2, I explained how to convert one character variable to a factor in R. In this example, I’ll illustrate how to convert all character columns to factor in R. Let’s duplicate our example data again: data3<-data# Replicate example data frame ...
