Keep this in mind, when you convert a factor vector to numeric! I’ve seen this mistake quite often in the past. Programming Video: Further Examples Check out the following video, in case you needfurther explan
To use R to test if the two factors, sex and affiliation, are statistically independent, you’d first place the data into a numeric matrix with this command: XML > cm<-matrix(c(15,30,25,15,10,5),nrow=2,ncol=3) Notice that in R, matrix data is stored by co...
Or we want to convert the factor into a numeric vector: We will use as.numeric() Code. as.numeric(direction.factor) Output: Recommended Articles This is a guide to Factors in R. Here we discuss the introduction, Advantages of a factor, How to create a factor in R along with the Outpu...
Example 1: Reproduce the Error – unexpected numeric constant in X In this Example, I’ll illustrate how to reproduce the error “unexpected numeric constant in X” in the R programming language. Have a look at the following R code:
been stored as characters, i.e., columns a and b. Notice that column c is not a character column, rather it is afactor. Our method here converts the factors into numeric as well but to get more information on why this works, I encourage you to readconversion of factors to numeric. ...
You can set the use.value.labels argument to FALSE, if you wish to not convert value labels variables to R factors. Also, to.data.frame argument can be set to TRUE to receive output in data frame display. 2. STATA FILES You can import stata files to R via foreign package through the...

In this post, we will show how to create vectors, factors, lists, matrices and datasets in R Vectors The vector is a very important tool in R programming. Through vectors, we create matrix and data frames. Vectors can have numeric, character and logical values. The function c() is used...
The c() function can be used to create vectors of objects. Using the vector() function > x <- vector("numeric", length = 10) > x [1] 0 0 0 0 0 0 0 0 0 0 Mixing Objects Mixing Objects > y <- c(1.7, "a") ## character ...
Objects and Attributes #===# ## Object # character # numeric(real number) # integer # complex # logical(True/False) # The most basic object is a vector # A vector can only contain objects of the same class # BUT: The one exception is a list, which is represented as a vector # t...
