Re: [R] How to define proper breaks in RFM analysis

Hi Your statement about attaching data is problematic. We cannot do much with it. Instead use output from dput(yourdata) to show us what exactly your data look like. We also do not know how do you want to split your data. It would be nice if you can show also what should be the bins with respe

Re: [R] comparing two strings from data

One additional comment. If you want 0 instead of NA when there is no match then the match statement should read: match_list <- match( data_2$data1, data_2$data2, nomatch=0) On Fri, Oct 13, 2017 at 7:39 AM, Eric Berger wrote: > Combining and completing the advice from Greg and Boris the comple

Re: [R] comparing two strings from data

Combining and completing the advice from Greg and Boris the complete solution is two lines: data_2 <- read.csv("excel_data.csv", stringsAsFactors = FALSE) match_list <- match( data_2$data1, data_2$data2 ) The vector match_list will have the matching position when it exists and NA's otherwise. Its

Re: [R] comparing two strings from data

It's generally a very good idea to examine the structure of data after you have read it in. str(data2) would have shown you that read.csv() turned your strings into factors, and that's why the == operator no longer does what you think it does. use ... data_2 <- read.csv("excel_data.csv", strin

Re: [R] comparing two strings from data

The error is because the read.csv function converted both columns to factors. The simplest thing to do is to set stringsAsFactors=FALSE is the call to read.csv so that they are compared as strings. You could also call as.character on each of the columns if you don't want to read the data in again

[R] comparing two strings from data

Hi, I have two columns that contain numbers along with letters (as shown below) and have different lengths. Each entry in the first column is likely to be found in the second column at most once. For each entry of the first column, if that entry is found in the second column, I would like to get

Hi Lisa, I'm not sure exactly what sort of plot you want, but this may help: rcol<-matrix(c(1,0,3,1,0,4,0,0,1,0,5,6),ncol=4,byrow=TRUE) # replace zeros with NAs as there is no numeric color for zero rcol[rcol==0]<-NA library(plotrix) color2D.matplot(rcol,cellcolors=rcol,yat=1:3) Jim On Fri, Oct

[R] dual y-axis for ggplot

Hi, To my knowledge, an excellent of ggplot with a second y-axis is https://rpubs.com/MarkusLoew/226759 In this example, the author uses two colors for the two lines, but the line shapes are the same -- both are solid. Could each line have its own color as well as its own shape? For exampl
