Conditions with a chain of functions In practice, we usually write functions that call other functions, and it can get confusing if there isn’t an easy way to find the source of the error in nested functions. Let’s define two functions as an example. The first,sim_valuewill simulate ra...
Creating multiple cursors via shortcuts like Ctrl + Shift + Up / Down; Ctrl + Shift + A; Ctrl + Shift + L, Switching back and forth from Visual Mode to Source Mode, Clicking around within chunks. Let me know if this rings any bells, or sounds similar to how you all might be encou...
It should be fixed in the daily builds of RStudio, if you want to test:https://dailies.rstudio.com. We also hope to fix this with the v1.3 release of RStudio. As an aside: I cannot reproduce this crash in my Ubuntu 20.04 VM. What version ofglibcdo you have installed? For example...

In Lesson 21, we learned how to do a multiple linear regression analysis. Any conclusions from that analysis to a population of interest (all countries) will only be valid if certain conditions exist. In this lesson, we will discuss what those conditions are and how to assess them. ...
If you can get a project to deterministically get this issue, it would be helpful to try it on a different machine or a newer RStudio version. If that still happens, you have a great test case to give RStudio to work with! mikebessuillereopened thisApr 14, 2022 ...
Let me know if there is anything else you need. pthread_cond_timedwait returned 22 Error in execCallbacks(timeoutSecs) : Condition variable failed to timedwait Stopped Radiant Messages shown in console: > traceback() 15: stop(e) 14: (function (e) { if (is.null(attr(e, "stack.trace...
The slope of the regression line simply reflects the difference in means between the two conditions since scr is now a 0/1 variable. The intercept is equal to the mean in the first condition. Note that the slope wouldn't change if we were to code scr as ½ instead of 0/1, but ...
Extracting Multiple Elements at a Time Everything we have done above extracts the value of a single element. We did this for a single file, we did this for files with multiple records, we did this for multiple files, and we did this based on certain conditions. What if we want to extr...
Multiple Conditions You can chain multiple if statements together:Hide if (this) { # do that } else if (that) { # do something else } else { # do this } If you end up with a large series of if statements, better use switch() function. It allows you to eavluate selected code ...
