Fitted Model Line is looking very wrong. Fitting a Quadratic Regression Line to a plot

I am trying to plot a quadratic regression line over a plot. This is the plot currently: This is the code I have tried: I think it is quite self explanatory with the picture. model7<-lm(count~distance+I(distance^2), data=data) summary(model7) plot(count~distance, data=data) lines(fitted(model7)) >Solution : You could make a new dataframe and then add it to the plot… Read More Fitted Model Line is looking very wrong.

Evaluating boolean expression over the columns of a matrix against the elements of a vector in R

I have a matrix of data, where I want to check whether or not the absolute value of each column falls within a certain range. Moreover, I would like to calculate the proportion of times it occurs across all columns. I know how to do this manually but I would like to write this generally… Read More Evaluating boolean expression over the columns of a matrix against the elements of a vector in R

R Software: Creating a table of r-squares from a table with multiple data series

I have a data.frame with multiple columns in it. The first in the frame is the dependent variable and the other columns are various independent variables. I’d like to create a table with all the R2s where column1 is y, and the each column is a different x. Here’s an example data.frame: df <- data.frame(… Read More R Software: Creating a table of r-squares from a table with multiple data series
