These operations are applied element-wise. Example # Numeric vector operations vector1 <- c(1, 2, 3) vector2 <- c(4, 5, 6) # Addition result_add <- vector1 + vector2 # [5, 7, 9] # Subtraction result_sub <- vector1 - vector2 # [-3, -3, -3] # Multiplication result_mul...
sapply() function takes list, vector or data frame as input and gives output in vector or matrix. It is useful for operations on list objects and returns a list object of same length of original set. sapply() function does the same job as lapply() function but returns a vector.sapply和...
matrix ## Similarly, subsetting a single column or a single row will give you a vector, ## not a matrix(by default). x <- matrix(1:6,2,3) x[1,] x[1,,drop = FALSE] #===# # Subsetting R Objects: Subsetting with Names #===# ## Partial Matching ## Partial matching of ...
For loop is one of the control statements in R programming that executes a set of statements in a loop for a specific number of times, as per the vector provided to it. The basic syntax of a for loop is given below for (value in vector) { statements } For example: v <- c(1:5...
Using R, you can manipulate a vector by adding or subtracting elements. You can also use the “repeat” function to repeat the elements of a vector several times. You can also use the “subset” function to select the elements you want to include in a vector. ...
When two vectors of the same length are involved in arithmetic expression, R will perform the operations element by element (vectorized operations). If they are of different lengths, R will cycle in the shorter vector (Note that a single number can be viewed as a vector of length 1). And...
It covers R’s functions and data types, vector operations and advanced functions like sorting. You’ll learn how to apply general programming features like conditional construct “if-else,” and “for loop” commands, and how to wrangle, analyze and visualize data....
## a sequence or vector. For loops are most commonly used for iterating over ## the elements of an object(list,vector,etc.) for( i in 1:10){ print(i) } # This loop takes the i variable and in each iteration of the loop gives it ...
R语言 把一个对象转换成一个矢量 - as.vector() 函数 R语言中的 as.vector() 函数用于将一个对象转换成一个矢量。 语法: as.vector(x) 参数: x: 要转换的对象 例1 : # R program to convert an object to vector # Creating an array x <- array(c(2, 3,
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 > y <- c(TRUE, 2) ## numeric > y <- c("a", TRUE) ## character ...
