Q: How can I check the type of a variable in R? A: You can use the class() function to determine the type or class of a variable. This function will return values like "numeric", "character", "factor", and so on, depending on the variable's type. Q: I mistakenly assigned a ...
In Example 1, I’ll demonstrate how to add a new empty variable to a data frame that contains blank character strings.For this task, we can use the R code below:data$new1 <- "" # Add empty character string data # Print updated data frame...
In a regression analysis,if a new independent variable is added and R-squared increases and adjusted R-squared decreases precipitously,what can be concluded?在回归分析中,如果有一个新的变量x加入,那么r的平方增大,同时调整r方减小,以下推论哪个是对的The new independent variable improves the predictive ...
