Removing (or renaming) this directory will reset RStudio's state. This directory includes information about open documents, log files, and other state information. If this directory does not exist, RStudio will create it on start up. RStudio Desktop stores its internal state in a hidden directory called RStudio-Desktop. They can be restored by dragging the gripper that separates the right panes from left panes. The cause of this problem is usually that the right panes have been minimized. It may sometimes appear as though RStudio has lost its rightmost two panes (for instance, you can see the Script and Console panes, but not the Environment or Plot pane). If the above approaches do not solve your problem, try reproducing outside of RStudio. If you have multiple graphics devices open, repeat this command until the output displays null device. For example: myplot dev.off() Note: This will delete your current plots in the RStudio Plots Pane. In alternative, if this code is inside a function, you will have to print it explicitly. You are probably plotting to a null device. Once you've had a go at that it will be more encouraging for people on here to help you out. This doesn't look minimal If the issue is that ggplot will not create a line, start by trying to debug that, outside of a Shiny instance. We ask for minimal reproducible examples. Straight up, this strikes me as a ggplot question, not an R Shiny question. Values with asp > 1 can be used to produce more accurate maps when using latitude and longitude. The special case asp = 1 produces plots where distances between points are represented accurately on screen. To use this parameter, you need to supply a vector argument with two elements: the number of rows and the number of columns. To put multiple plots on the same graphics pages in R, you can use the graphics parameter mfrow or mfcol. Keep RStudio focussed on 'Source' and 'Plots' when executing code line-by-line.īy Andrie de Vries, Joris Meys. Make R Studio plots only show up in new window. Starting the viewer You can invoke the viewer in a console by calling the View function on the data frame you want to look at. The viewer also allows includes some simple exploratory data analysis (EDA) features that can help you understand the data as you manipulate it with R. if the length of the vector is less than the number of points, the vector is repeated and concatenated to match the number required. R uses recycling of vectors in this situation to determine the attributes for each point, i.e. Plot symbols and colours can be specified as vectors, to allow individual specification for each point. The most common function for creating heatmaps in R is the heatmap() function, which is already provided by the base installation of R.Local web content is displayed in the Viewer pane by accessing the RStudio viewer function definition via getOption("viewer") This approach is front-end agnostic (other IDEs could define this option for alternative implementations of an internal viewer) and allows the user to override the default behavior if need be. So keep on reading until the end of the article!Įxample 1: Create Heatmap with heatmap Function It’s useful to know different ways to create heatmaps, since every package provides a different heatmap design. In the following examples, I’ll show how to create heatmaps in R based on different functions and packages. Our data contains ten columns and ten rows with normally distributed random values. Rownames(data) <- paste0("row", 1:10) # Row names Set.seed(123) # Set seed for reproducibilityĭata <- matrix(rnorm(100, 0, 10), nrow = 10, ncol = 10) # Create example dataĬolnames(data) <- paste0("col", 1:10) # Column names Rownames (data ) <- paste0 ( "row", 1 : 10 ) # Row names seed ( 123 ) # Set seed for reproducibilityĭata <- matrix (rnorm ( 100, 0, 10 ), nrow = 10, ncol = 10 ) # Create example dataĬolnames (data ) <- paste0 ( "col", 1 : 10 ) # Column names
