"Hi again!
I wanted to find the correlation between RateA and RateB. I've tried the method using regression. Is there any other method that I can use to find the correlation?
Another scenario here. The above one was RateA and RateB, both…"

"You can use more conditions in the subsetting.
e.g. RateA[RateA >40 & RateB < 40 & RateB > 40 & RateB<50]
You didn't tell us anything about your problem. What is the target variable?
Regression methods are for numeric…"

"Hi. What if for now i would like to plot the Rate between 40 to 50. How do I type the command.
I'm a little confused by the operators to use for between.
Also, other than linear regression. I can also use association or classification…"

"I think that the following command that will do the plot,
plot(RateA[RateA<150 & RateB<150], RateB[RateA<150 & RateB<150], data=data.table) .
I am not sure if you can use the data=data.table in plot the same…"

"Hi!
Yes, this is exactly how you use linear regression to analyse the (linear) relationship between two variables.
The most interesting output from summary() is the (Intercept) line and the one below that, starting with RateB. The Estimate…"

"rnorm(50) gives you 50 random numbers.
It was an attempt to create a dataset that has the same structure as your dataset.
You can't plot vectors with differing lengths. This is why the plot(ra, rb) command fails. Your original attempt, if it…"

plotting of graph in R
Hi all. I would like to plot a graph maybe Rate A against Rate B. however I only wants the value less than 150. I tried using the command however the outcome wasn't what i expected. > plot(data.table$RateA >150, data.table$RateB > 150) any help?See More

"Hi Gen!
Another scenario was what if i wants to plot only variable that is less than 200?
I used the plot(data.table$money > 200) however I felt that it wasn't the graph i wanted.
any help?"

"I do have more than 200 names. The example stated above is just an example. I have more than 1000 names in my database.
Do you have any idea how to plot the graph base on first letter of the name?"
Amy replied to jadelim's discussion plot a graph by first letter of variable in R in the group Data Mining
"I am assuming that you have more than 200 names, otherwise your analysis would be weak. Better, if you have 5000 names broken down per country, then you could provide great visual insights."

plot a graph by first letter of variable in R
Hi all, I am very new to R and is not familiar with R scripting.may i know is it possible to plot a graph by first letter? for example: Name: Age: Angel 20 Amelia 20 Bernard 19 Stephanie 20 Vanessa 22 Angeline 23 Camel 21 If I want to plot the name started with letter 'A' and their Age, how is it possible to plot it? Thanks.See More
