Importing excel and graphing

[Buckeye]

If you didn't know you can run the examples from the documentation directly using

example(boxplot)

[/code]

Does this work for anything? Like anything I can put a '?' in front of?

Well - anything that has an examples section in the documentation. And as long as the examples aren't surrounded in \dontrun tags. But yes - it's a nice way to see some examples of functions being used without having to copy/paste everything directly.

I copied and pasted this from a link - since I am brand new to plotting. I will try to find the link and paste it here. I told 3 people who expressed an interest in learning R this webpage. They are learning from me which (beyond brining laughter here) is less than ideal.

I am having trouble with data labels in bar charts.

This should work, but does not center correctly perhaps because of the type of bar chart I am using.

library(gcookbook)
                  library(ggplot2)
ggplot(cabbage_exp,aes(x=Date,y=Weight,fill=Cultivar))+ geom_col(position=position_dodge(.7),width =.5)+geom_text(aes(label=Weight),vjust=-.02)

I don't understand why this does not work (I get a blank chart with a Y and x axis).

 library(gcookbook)
 library(ggplot2)
library(dplyr)
library(tidyverse)
climate_mod<- climate %>%  filter (Source=="Berkley")%>%  select(Year,Anomaly10y,Unc10y)
 ggplot(climate_mod, aes(x=Year,y=Anomaly10y))+ geom_ribbon (aes (ymin=Anomaly10y-Unc10y,ymax=Anomaly10y + Unc10y),alpha=.2)+geom_line()

I get a dataset with 0 observations when I run the above code. "Berkley" is misspelled.

climate_mod<- climate %>%
  filter(Source=="Berkeley") %>%
  select(Year,Anomaly10y,Unc10y)
ggplot(climate_mod, aes(x=Year,y=Anomaly10y))+ geom_ribbon (aes (ymin=Anomaly10y-Unc10y,ymax=Anomaly10y + Unc10y),alpha=.2)+geom_line()

I thought I copied and pasted it from the book I was working from but apparently not. I am surprised I don't get an error.

One of the hardest things for me in R as compared to SAS. Spelling matters so much.
