The htmlTable-package. I developed the htmlTable in order to get tables matching those available in top medical journals. After finding no HTML-alternative to the Hmisc::latex function on Stack Overflow I wrote a basic function allowing column spanners and row groups. Below is a basic example on these two.

NASA Risk Matrix. Whenever program or project risk is being identified, it is a common practice at NASA, like many other organizations to use a 5 X 5 risk matrix with a green, yellow, red coding for visualization of the risk. Recently a colleague asked for help in visualizing the matrix in Excel. She wanted assistance in pivot tables, sorting, macros and chart building. Stop the insanity.

II.Matrix A matrix is a two dimensional array, it consists of elements of the same type and displayed in rectangular form. The first index denotes the row; the second index denotes the column of the specified elements, i.e. X ij represents the element in the i th row and jth column. A) Creating matrix The following table has some related R functions Function Description Example matrix.

Details. This is an enhancement to rbind that adds in columns that are not present in all inputs, accepts a list of data frames, and operates substantially faster. Column names and types in the output will appear in the order in which they were encountered. Unordered factor columns will have their levels unified and character data bound with factors will be converted to character.

A discussion on various ways to construct a matrix in R. There are various ways to construct a matrix. When we construct a matrix directly with data elements, the matrix content is filled along the column orientation by default.

This is a case where you start by breaking down you complex one-liner into separate statements and examine what the results are at each point. This is what I would have to do with the script you posted. I think as Bill pointed out, one of your function calls is probably creating a result that you were not expecting. Standard (good) programming practice would have you creating a number of.

R Data Frame. In this article, you’ll learn about data frames in R; how to create them, access their elements and modify them in your program. Data frame is a two dimensional data structure in R. It is a special case of a list which has each component of equal length. Each component form the column and contents of the component form the rows. Check if a variable is a data frame or not. We.

DataFrame objects Description. The DataFrame class. If from is a matrix or data.frame, all of its columns become columns in the new DataFrame. If from is a list, each element becomes a column, recycling as necessary. Note that for the DataFrame to behave correctly, each column object must support element-wise subsetting via the (method and return the number of elements with length. It is.
