For that reason, in the output vector its name is l12 (i.e. l1 + 2).If you want to get rid of these names, you can simply add the specification use.names = FALSE within the unlist R function:unlist(my_list, use.names = FALSE) # Apply unlist without names # 1 7 3 5 5 3 ...
Example 1: Get List of Full Directory Paths Using list.dirs() Function The following R programming code shows how to get a list of all subdirectories stored in a working directory on a computer. For this, we can apply the list.dirs function to the path of our working directory. Note th...
In R, we can use the length() function to find the number of elements present inside the list. For example, list1 <- list(24, "Sabby", 5.4, "Nepal") # find total elements in list1 using length() cat("Total Elements:", length(list1)) Output Total Elements: 4 Here, we have us...

You can use theapply()function in R to apply theas.numeric()function to every element of a data frame. The asnumeric function is pretty welcoming: it accepts strings that want to be integer(s) and floating point number values (floats). ...
To this end, I offer a set of functions which may be used to manipulate the order of multiple items in a DCL List Box. Each function requires a list of indexes of the items which are to be reordered, and a list of all items to be displayed in the DCL List Box. Following the reor...

In R String Functions, the regexec() function is similar to regexpr() with the difference that regexec() returns the indices of the corresponding sub-expressions enclosed in parentheses. Syntax :regexec(pattern, text, ignore.case=FALSE, perl=FALSE, fixed=FALSE, useBytes=FALSE) ...
