R will then install and unpack each component of the chosen package. to ensure quick download speeds, then click ok. This displays the list of packages available to downloadĬhoose a mirror(download server) somewhere in the U.S. To download a package, click the Packages drop-down menu, then select Install package. These pieces of content are organized into packages. This is a file server which allows you to download new content for R. In R, such packages can be installed using the CRAN(Comprehensive R Archive Network) mirror from the main console. Packages are add-ons that extend the functionality of software. This code will display the working directory under the line of code as shown in Figure 1-6 below. To find the directory R is using, use the code getwd(). NOTE: In order for R to properly read and locate the file it MUST be placed in the local directory. CSV files store tabular data into plain text form, which makes importing from excel much easier. In this example we will be importing a comma separated values file which has an extension of. R can handle several types of data, including numbers, character strings, vectors and matrices, as well as more complex data structures.To open a script in R, under File, select Open Script, then choose the location of the file. In Figure 1-3 and Figure 1-4 below, you will see examples of a sample script and a complex formulation of code. ![]() If you can make yourself familiar with some common syntax, it can be a very powerful tool with statistical analysis. Every line of code is a unique function that has a purpose. R needs to be told what to do using code. Unlike SPSS and STATA, there is little to accomplish through R’s menu bar. Stops current computation(R will continue to compute most recent code until it is stopped) 3.01īelow is a list of the buttons from the main interface along with a description of their function: This is the main menu of the R interface as of Ver. R uses a command line interface however, several graphical user interfaces are available for use such as Rstudio and R Commander. The source code for the R software environment is written primarily in C, FORTRAN, and R itself. R is a GNU project, which grants users the freedom to take control over their software through sharing, collaboration, and modification. This means an unqualified name can be completely determined by looking at the program text. R is an implementation of the S programming language combined with lexical scoping. I don't want to experiment with that until I'm certain I have a good copy of the RAID data.Training Homepage | Tutorial Main Menu | Using R for Basic Calculations But other posts say this is a very bad idea that can destroy data on the disks. Any advice would be most appreciated!Īlso, does anyone have any guidance on re-creating the RAID array in the computer's BIOS administrator? I've seen some posts in the ASUS motherboard forums in which people say they just turn on RAID after doing a BIOS update and their old RAID array magically re-appears. ![]() ![]() I've tried adding all four disks to a Virtual RAID object in R-Studio (choosing the RAID 10 option), but after 24 hours R-Studio indicates it has only processed 60 MB of data (on four 2 Terabyte disks), so I suspect I'm doing something wrong there. I see no way to implement step 7 of these instructions. Generated by ReclaiMe Free RAID Recovery build 2228, However, these instructions are for version 5.1 of R-Studio, not the current version 8.1. On the left panel, "Virtual Block RAID 1" is the newly created RAID. In the "Parents" table, enter "0 Sectors" as "Offset" in all rows.Ĩ. Below that, set "Block size" to "64 KB".ħ. On the right side of the R-Studio window, set "RAID type" to "RAID0 (Stripe set)".Ħ. Right click the disk list on the right, select "Add Disk 4 - ST2000DM006-2DM164 : ZC3N8M" from the pop-up menu.ĥ. ![]() Right click the disk list on the right, select "Add Disk 2 - ST2000DM006-2DM164 : ZC3NR8" from the pop-up menu.Ĥ. Then, select "Create Virtual Block RAID" from the dropdown menu.ģ. On the toolbar, click "Create Virtual RAID". These instructions are provided for R-Studio version 5.1Ģ.
