Write a function rescale that takes a vector as input and returns a corresponding vector of values scaled to lie in the range 0 to 1. The filter() method in R can be applied to both grouped and ungrouped data. So, We go through the Marks column and stop Where the name connected to those marks is Sita. as.numeric() function: This function is used to convert a given column into a numeric value column in r language. (If L and H are the lowest and highest values in the original vector, then the replacement for a value v should be (v-L) / (H-L).) You can do the following: The keys of this list define the column names of the table, and the types are inferred by sampling the whole dataset, similar to the inference that is performed on JSON files. The values can be mapped to specific occurrences or within a range. Output: Explanation: Using the sapply() method, the class of the col3 of the dataframe is a character, that is it consists of single-byte character values, but on the application of transform() method, these character values are converted to missing or NA values, because the character is not directly convertible to numeric data.So, this leads to data loss.
