问题 I screwed up a ggplot function and ran this wonky line all by itself: label = as.character(share)+'%"), -- and then I didn't realize the cursor was showing a + instead of > so I ran the whole ggplot function again and only then noticed that the console was looking for more input. I did figure out what was wrong (I needed to close the ' and " I had opened) but I couldn't figure out how to just exit the function entirely. I tried ctrl c and every "exit" command I could think of: + break + } + }

问题 I want to remove the check all/none checkbox from a Reactable table. In this image, I do not want the orange circled checkbox to appear. Using Chrome Inspector, I examine the css of this checkbox and set display: none; This removes the entire column of checkboxes. How do I remove just this one? R Script library(reactable) reactable(iris, onClick = "select", selection = "multiple") 回答1: U can append some javascript code and make it run when the reactable is rendered: ie // Hide the select all

问题 How can I draw a barplot for means, while controlling for other variables through regression -- in a split-bars-by-vars fashion? My general problem I conduct a research to figure out which fruit is more likable: mango, banana, or apple. To this end, I go ahead and sample 100 people at random. I ask them to rate, on a scale of 1-5, the degree of liking each of the fruits. I also collect some demographic information about them: gender, age, education level, and whether they are colorblind or

The issue is that I can get a succesfull connection outside of the shiny environment but when I try to do this via shiny and rmd I get: Error : nanodbc/nanodbc.cpp:1021: 01S00: [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'bpsrawdata'.

问题 I am using a Montecarlo simulation for predicting mpg in the mtcars data. I want to extract the coefficients of all the variables in the dataframe to compute how many times each car has lower mpg than the other car. For example how many times Toyota Corona has less predicted mpg than Datsun 710. This is my initial code using only two independent variables. I want to expand this selection to use all the variables in the data frame without manually have to include all the variables in the data

问题 I'm trying to make multiple lollipop plots using a facet wrap, like in the third code block / example and picture below on this page. However, I can't get the code example to work. Can you please help me see where it is written incorrectly (if at all)? The data: set.seed(1) data <-as.data.frame(matrix( sample( 2:20 , 40 , replace=T) , ncol=10)) colnames(data) <- c("math" , "english" , "biology" , "music" , "R-coding", "data-viz" , "french" , "physic", "statistic", "sport" ) data <-rbind(rep

问题 I want to find a way to replace consecutive same values into 0 at the beginning of each trial, but once the value has changed it should stop replacing and keep the value. It should occur every trials per subject. For example, first subject has multiple trials (1, 2, etc). At the beginning of each trial, there may be some consecutive rows with the same value (e.g., 1, 1, 1). For these values, I would like to replace them to 0. However, once the value has changed from 1 to 0, I want to keep the

问题 This question already has answers here : replace a specific strings from multiple columns in a dataframe (4 answers) Closed 1 year ago . Could you help me please for answer the little Q? I have data.frame like under. than, I want to use gsub function specific column in data.frame easily Because the change character is SAME! but I want change lots of specific column. In example code, It have just 4 column but my data have over 10 column, and I want change 6~7 specific column (not continuous).

问题 I have been learning r for a few days, and I am trying to do a specific output and I can not figure out how to select days prior to an event. I am trying to determine how recharge events impact detections of a containment in water samples. I have data that has 7 columns (Date, month, day, year, samp, prcip, snow) where the date is YYYY/MM/DD, month, day, and year are what they say, samp has a 0, 1, or NA, and both precip and snow have daily totals for either rain or snow. There is 1 row for
