...degree~C),cex=1) This worked great and resulted in the symbol for degree. In the function, I have changed it so: text(1,1,paste(b_unit),cex=1) and b_unit<-expression(~degree~C) This now inserts ~degree~C instead of the symbol. Any advice?

Hello, I have two plots on the same screen. I use the command par(mfrow=c(1,2)) in order to do this. When I try to make a legend for both plots, it only puts the legend in the plot on the right side. If I would like a legend that is outside of both of the plots, how would I do this? Thanks [[alternative HTML version deleted]]

Dear List, I am using the command plot to present the relationship between bird richness (Y axis) and elevation (X axis). However, I would like to observe the distributions of bird richness in different administrative areas (A, B, C, …., G) in this plot. For example, the dots in area A might fall in the upper right part of the plot, while those in area B might appear in the middle of

Hello, I am trying to cycle through a csv and make some summary statistics. I need to select rows based on the number in the row name that comes after the letter 'y'. For example, ? BA1y1 would equal 1, ?C3A2r3y1 would equal 1 and ?MA3r3y1r3 would equal 1. I currently have my code ?cycling through by the 5th character but my rows have variable length and the y can occur in several

Hey guys, I've search a few threads about deleting a value from a vector, but no one has addressed this question so far. I want to delete the last value from a string of values I have: r = [ 1, 2, 3, 4, 5 ], and i want to make r2 = to [ 1, 2, 3, 4] So that r2 is just like r, except that it missing the final value.

Hello, I think this is a simple problem but I am not coming up with a simple solution. I think it just an indexing problem. I can easily replace values in a matrix from a dataframe when the dataframe has row and column numbers. In the example below I use row and column names and I can not get it to work #make a matrix where rows and columns are the lat and long for a bounding box of Australia

Hi, I want to impute the missing values in my data set multiple times, and then combine the results (like multiple imputation, but manually) to get a mean of the parameter(s) from the multiple imputations. Does anyone know how to do this? I have the following script: y1 <- rnorm(20,0,3) y2 <- rnorm(20,3,3) y3 <- rnorm(20,3,3) y4 <- rnorm(20,6,3) y <- c(y1,y2,y3,y4) x1 <-
