R matching lat/lon pairs from two datasets?
Hello, I am trying to match lat/lon from one dataset with the lat/lon from a second dataset and use that rows data for calculations. I am using match, but this is finding the first match and not comparing the pair, how can I determine if the lat/lon are the same? See example below. Is there a better way to determine to a matching pair of lat/lon values? Example Datasets: > data2

paste name in for loop?
Hello, I am trying to create subsets of grouped data (by area size), and use the area size as part of the output name. The code below works for area (xout) 1 and 50, the other files are given NA for an area. A simple example: xout <- c(1,5,10,25,50,100) for(i in xout) { print(paste("Areal_Ppt_",xout[i],"sqmi.txt", sep="")) } [1] "Areal_Ppt_1sqmi.txt"

Data frame search and remove questions
Hello, I have a couple questions about removing rows from a data frame and creating a new data frame with the removed values. I provided an example data frame (d) below. Questions: 1) How can I search for "-999.000" and remove the entire row from data frame "d"? (all -999 values will be in sd_diff) 2) Can I create a new data frame "d.new" that only contains the

R for loop question
Hello, I am trying to assign a variable name (x1,x2,x3...) in a loop statement that is based on a counter (counter is based on the number of hours within the datafile). The x1,x2 data will later be called for plotting the data. Below is a clip of the for loop I am using, any suggestions? k = 1 for (i in 1:length(stats$hour)) { "x(i)" = dataset[k,(3:15)] k = k+1 } Thanks,

Cairo package, png files within for loop are black?
Hello, I am generating .png images using the Cairo package in a for loop (looping on the number of zones, number of zones equals the number of plots to create based on different zone data). When I run the R script the .png files are created but they are all black? If I comment out the for loop and force my zones to equal one the png file is created correctly? Is there an issue with

New vector based on if/else statement within for loop?
Hello, I am trying to create a new vector (w) that is based on comparing two vectors (P and Z). The compaison is simple (I created a for loop that reassigns w based on if statement), all Z values >= 24 and P values <=1, w=88 else w=77. I am not getting the correct results for w, see example code below. Any thoughts or suggestions on the correct method. Thank you, Doug P <-
