How do you find the highest and lowest value in R?
We can find the minimum and the maximum of a vector using the min() or the max() function. A function called range() is also available which returns the minimum and maximum in a two element vector.
How do I remove duplicate rows in R?

How do you get top 5 values in R?
To get the top values in an R data frame, we can use the head function and if we want the values in decreasing order then sort function will be required. Therefore, we need to use the combination of head and sort function to find the top values in decreasing order.
How do you find the max and min of a column in R?
Min() and Max() Function in R
- min() function in R computes the minimum value of a vector or data frame.
- max() function in R computes the maximum value of a vector or data frame.
- column wise maximum and minimum of the dataframe using max() and min() function.
How do I find the lowest value in R?
Minimum value of a column in R can be calculated by using min() function. min() Function takes column name as argument and calculates the Minimum value of that column.
How do I filter unique values in R?
You can use the following methods to filter for unique values in a data frame in R using the dplyr package:
- Method 1: Filter for Unique Values in One Column df %>% distinct(var1)
- Method 2: Filter for Unique Values in Multiple Columns df %>% distinct(var1, var2)
How do I keep unique values in R?
The function distinct() [dplyr package] can be used to keep only unique/distinct rows from a data frame. If there are duplicate rows, only the first row is preserved. It’s an efficient version of the R base function unique() .
What is Panda argmax?
argmax() function returns the indices of the maximum value present in the input Index. If we are having more than one maximum value (i.e. maximum value is present more than once) then it returns the index of the first occurrence of the maximum value. Syntax: Index.argmax(axis=None)
How do you find rank in R?
If we have a matrix with dimensions R x C, having R number of rows and C number of columns, and if R is less than C then the rank of the matrix would be R. To find the rank of a matrix in R, we can use rankMatrix function in Matrix package.
