C in r

R does internal coercion such that the values are consistent with the simplest data type. logical < numeric < complex < characters. Let’s look at another example. Here, we will pass numeric and logical values to the c() function. # vector with mixed values in R vec <- c(1, 3, 5, TRUE, FALSE) # display the vector print(vec) Output: [1] 1 3 …

Additionally this function has some arguments with default values. How can I handle the either/or- arguments best. If "a" is provided I don't need "b" and "c" and vice versa, but at least one is needed. Two options come to mind using base R: x <- "c(123, 234, c(235), 3, 5, 6)" (I added the c(234) in the middle in order to show that the regex only affects the first/last chars in the string.)

Celsius a number indicating the true value of the mean (or difference in means if you are performing a two sample test). a logical indicating whether you want a paired t-test. a logical variable indicating whether to treat the two variances as being equal. In this example, the c function is used to combine two vectors (numbers and letters) into a single vector (combined_vector). The resulting vector contains the …Slicing with subset () We can slice data frames using the subset () method. The subset method accepts the data, filter logic to slice and the columns to fetch. The syntax of slicing with subset is –. subset ( x = dataframe, subset = filter_logic, select=c (columnNames)) R.R doesn't have these operations because (most) objects in R are immutable.

If your CSV file is reasonably small, you can just use the read.csv function from Base R to import it. When using this method, be sure to specify stringsAsFactors=FALSE so that R doesn’t convert character or categorical variables into factors. The following code shows how to use read.csv to import this CSV …

A quick note before going on to the third example is that readxl and dplyr, a package we will use later, are part of the Tidyverse package.

With the following code you can convert all data frame columns to numeric (X is the data frame that we want to convert it's columns): as.data.frame(lapply(X, as.numeric)) and for converting whole matrix into numeric you have two ways: Either: mode(X) <- "numeric". or: The c function is ubiquitous in r code samples. It’s a quick way to turn a list of argument values into an R vector, one of the essential building blocks (along with the data frame) of core R code. But the c function is more than just a R vector constructor. Note that in R < 4.1.0, factors were treated only via their internal integer codes: now there is c.factor method which combines factors into a factor. c is sometimes used for its side effect of removing attributes except names, for example to turn an array into a vector. as.vector is a more intuitive way to do this, but also drops names.
