Graphics, Figures & Tables ⇒ ggplot2 fails to compile

[Mike Poletika]

Hello,

I have a series of ggplots that successfully compile into my pdf, and two that do not. The code is identical among the different plots, except for the directories and file names. I get this error message: Error: unexpected '@' in "@". If someone could give me an idea of what I can do to solve this problem, I'd greatly appreciate it. I'm very new to LaTeX, so a simple explanation would be great.

Thanks,

Mike

This one works:

Code: Select all

<<echo=FALSE, fig=TRUE>>=

library(foreign)
library(ggplot2)

#read tables in 
school1 <- read.dta("C:/Users/Mike Poletika/Desktop/WFF SQM/INDIANAPOLIS/Report/Data/Datasets/schoolidA425/indianapolis_all.dta")

ggplot(school1, aes(growth, attainment))+
  geom_point(aes(colour = yrnstr), size = 3)+
  scale_x_continuous(limits=c(-1.35, 1.35))+
  scale_y_continuous(limits=c(-1.35, 1.35))+
  xlab("Growth")+
  ylab("Attainment")+
  theme(legend.position="bottom")

This one doesn't work:

Code: Select all

<<echo=FALSE, results=tex>>=
#Walton VAM Report#

library(foreign)
library(ggplot2)

#read tables in 
allschools <- read.dta("C:/Users/Mike Poletika/Desktop/WFF SQM/INDIANAPOLIS/Report/indianapolis_vam_all.dta")

ggplot(allschools, aes(growth, achievement))+
  geom_point(aes(colour = type), size = 3)+
  scale_x_continuous(limits=c(-1.35, 1.35))+
  scale_y_continuous(limits=c(-1.35, 1.35))+
  xlab("Growth")+
  ylab("Attainment")+
  theme(legend.position="bottom")

Hi and welcome,

not sure if anybody can be of any help here. We are a forum all around TeX and friends, a typesetting system to produce documents of high quality.

You can plot your data sets with LaTeX as well, have a look pgfplots to see some examples.

Hi Mike,

welcome to the forum! ggplot2 is plotting for R, LaTeX just imports the result.

You could directly plot within LaTeX, also large exported data files, have a look at http://pgfplots.net to see some examples and into the pgfplots manual. With this, some of us could provide help.

Also with any LaTeX related questions, of course.
