How to use RStudio efficiently

Summary. 1.Enter debug mode.

Select all** and click source to enter debugging mode.

How rstudio+ enters the debug state.

1.Enter the debugging mode, select all**, and click source to enter the debugging mode.

2.Enter for debugging in the for calendar band add browser() in the for, you can enter the for statement, and you can see the change of each value in the right rotten edge. For example: for().

3.Reference: Advanced:

Use the debugger debugging command with rstudio to encounter an interactive browsing bouncer when entering debug mode. There may be times when you want to not include breakpoints in your debugging, or you may need more advanced behavior, such as conditional breakpoints. In these cases, you can use the R debugging tool to make the interactive browser call the base detainment time, and once the browser is called, the rstudio debugging tool will become available.

The browser() command for conditional breakpoints ([url=] refers to [url]) can be inserted anywhere to create a breakpoint. Commands can be wrapped in an if declaration to make conditional breakpoints; For example: if (x ==0) browser()

The commands debug() and debugonce() url=] without breakpoints can be used to execute a function when setting a breakpoint. This makes it possible to set breakpoints on functions, and the source files are not out-of-the-box. Error breakpoints: It's sometimes useful to call the debugger when an error occurs.

To do this, there is a call to the browser by setting the error options(error = browser

Do you have any other questions? I'm glad to continue to answer for you The above is all my reply, I hope it can help you, I wish you a happy life Remember to like it! Thanks for your support!

Specific steps:1.In the first step, a vector n1 is fixed, and the function c is used to assign a value. Then call the square root function sqrt().

2.In the second step, the lead resistance vector n2 is determined, and the function c is used to assign the value. Then round down the function.

floor(),3.In the third step, Changyin uses the runif() function to generate a matrix, and then uses the matrix function to assign a value to n3,4The fourth step is to obtain the variance of the matrix n3, which represents finding the variance of each element in the matrix, 5

In the fifth step, if you sum the elements in the matrix n3, it means adding up all the elements and using the sum function.

6.Sixth, if you are required to take the arithmetic mean of the matrix object.

Use the mean() function.

To install rstudio, the total mammost core is divided into two steps: 1. Install the r installation package. 2. Install rstudio.

1. Install the R installation package.

2. Install rstudio.

Click "Download".

2.My computer is Windows10, so I chose the first one. You can choose different installation packages according to your different systems.

4.Click "Yes".

5.Click "Next".

6.Modify the installation path, generally set the road king on the D drive, not the C drive. (The installation path is set by yourself, and friends who install it for the first time can also do not need to modify the installation path.)

Use the default installation road force directly. )。

7.Click "Next".

8.Click "Install".

Test whether rstudio is successfully installed.

1.Click the Start button.

2.Click on "rstudiio".

3.Click "yes".

4.Enter "1+2" and then click the "enter" key to let ** run. If the output result is 3, then the installation is correct.
