I'm doing a density compare in R using the sm package (sm.density.compare). Is there anyway I can get a mathematical description of the graph or at least a table with number of points rather than a plot back? I would like to plot the resulting graphs in a different application, but need the data to do so.
Thanks a lot for the help,

Hi I am new to R and trying to learn. I would like to compare the overlap of 4 clusters which have the same 4 categories each in them. Basically, I am thinking of making a clustered heatmap like this image below that I quickly made as an example in excel. Does anyone know of an R package that would allow me to make a graph like this? So far, I have only found packages that limit you to one variable per X vs Y variable grid space. Thanks so much for your suggestions!
I've created a time series plot in R using the ggplot package, but I wanted to see if I could further customize it by creating target zones. I originally started with an Excel plot that allows me to move a gray box to different areas of the plot as an easier way to point out a range of temperatures. However, I wanted to see if I could replicate this in R. Here's a screenshot of my Excel plot to better explain my goal: Time Series on Excel. On the time series plot, you can see a gray box that you can drag around and change the size of to better define a range of temperatures (in this case, it covers from 15-25C). Is this possible to do on top of my time series plot in R? I'm only starting to code in R so it's been quite hard for me to navigate, and I appreciate any help I could get. Thanks!
Our instructor assigned us with typing a R script. We don't have any study paper or source for the codes that the instructor typed on class so I'm trying to get help from the articles on internet but I still couldn't find a guide for what I need. Please don't get me wrong, I don't request for someone to do my homework I'm just looking for some tips or any guide links that can help me. When I search on google, not all of the results are related to this and they are usually not helping me or too complicated. The assignment is:
Read data from a .txt file. (I researched and learned how to read data but my problem is I don't know which type of data should I type on the text file to make it plottable by average, standart deviation, histogram etc.)
On the first screen, plot the data, plot the average and plot the standart deviation as line
on the second screen, plot a line from corner to corner and sort the values on it
third screen, plot the data as histogram and plot the distribution function on it
4th screen, plot the anomaly and anomaly line = 0, then make the values that are higher than the anomaly line with different pch than the ones that is lower
finally get the png of 4 screens (i found how to do this)
Thanks.
Which type of data?
You should use metric data. For example the height/age of pople.
For example let's assuhe you have a dataframe yourDataframe:
height
160
155
176
153
185
On the first screen, plot the data
You can use R's standard plot function there: lines(yourDataframe$height)
plot the average and plot the standart deviation
There are already function for those things (for example mean(yourDataframe$height)). Just ask Google.
You can add those values to your linechart using points(mean(yourDataframe$height)).
I think after you did this you will be able to solve the rest of your assignment by yourself. R has quite a big community and you will find everything you need by googling. I guess this is how most people learn R.
Apologies, this is probably the simplest question. I'm having trouble making a scatterplot in R Studio. I am trying to see if amphipod counts are correlated to oxygen content. Whenever I plot this using:
plot(Amphipod~Oxygen...ml.l.)
I get a graph with boxes around certain points and I have no idea why. Only 5 points and I can't see anything different about those.
I have a small data set consisting of two columns of data and a column designating which of the two sites the data was taken at. I have used xyplot to sort by groups, but I can't figure out how to alter the symbology of each group separately. I also need to add a regression line, and can only figure out how to do that in plot. What graphics package can give me these features in the same graph?
I have looked into different graphics packages to find one in which I can do everything I need, but I am new to R and am not having much luck.
ggplot2 is your go-to.
Try this:
install.packages('ggplot2')
library(ggplot2)
one=c("A","B","A","B")
two=c(1,2,3,4)
three=c(5,7,8,20)
df<-data.frame(one,two,three)
ggplot(df,aes(x=two,y=three,col=one))+geom_line()
