To convert a list to a numeric value in R, you can combine the unlist() function and the as.numeric() function. The unlist() function produces a vector that contains all the atomic components, and the as.numeric() returns a numeric value or converts any value to a numeric value. Syntax as.numeric(unlist(data)) Parameters Argument Description data It represents the list … Read more
The lwd in R is used to specify the width of plot lines. It is a parameter that can be set in various plotting functions, such as plot(), lines(), abline(), etc. Syntax of lwd parameter plot( x, y, pch = 1, cex = 1, col = 1, bg = 0, lwd = 1, lty = … Read more
To convert a double or float to an integer, you can use the “as.integer()” function. Syntax as.integer(x) Parameters x: It is the object. Return value It returns an integer object. Visual representation Example 1: Converting a float to an integer r_float <- 11.21 print(r_float) print(typeof(r_float)) r_int <- as.integer(r_float) print(r_int) print(typeof(r_int)) Output [1] 11.21 [1] “double” … Read more
The dirname() function in R is used to extract the path to the directory from a full file path. Essentially, it returns the directory part of a file path, excluding the file name. This function is often used in conjunction with other file-handling functions like basename() (which extracts the file name) and file.path() (for constructing … Read more

The seq_along() function in R is used to generate a sequence of integers along the length of its argument. Syntax seq_along(len) Parameters len: It takes a length as an argument. Return value It returns an integer vector unless it is a long vector when it will be double. Example 1: Basic usage of seq_along() seq_along(LETTERS[1:5]) … Read more
Pi is a built-in R constant with a value of approximately 3.141593. It is the ratio of the circumference of a circle to its diameter. Syntax pi Basic usage print(pi) # [1] 3.141593 Exponential value of pi To calculate the exponential value of pi, use the exp() function. exp(pi) # [1] 23.14069 Cos To calculate … Read more
