I'm trying to make scatter chart, but error message occurs and can't knit.
{r}
ggplot
(railgun,aes(smile, voteshare)) geom_point()
Then [ Error: unexpected ',' in "(railgun,"] came out.

I referred to left side of page, but it won't work.
I know [,] is the wrong spot, but how can I replace other things?

This is the end goal however when trying to plot the code below
plot(PCAloadings[,1:2], arrows(0,0,PCAloadings[,1],PCAloadings[,2]), text(PCAloadings[,1:2], labels=rownames(PCAloadings))
I recieve the following error:
in text.default(PCAloadings[, 1:2], labels = rownames(PCAloadings)) : plot.new has not been called yet
I am unsure how to resolve this issue or what it pertains to, any help is welcome.
EDIT: when trying to run line by line only the first line runs. When trying to run arrows or text lines I run into the same error
plot(PCAloadings[,1], PCAloadings[,2])
This is the output from the first line alone
Seems to be a syntax problem. Try
plot(PCAloadings[,1:2])
arrows(0,0,PCAloadings[,1],PCAloadings[,2])
text(PCAloadings[,1:2], labels=rownames(PCAloadings))
I found this error when I was dealing with the swirl assignment:
You're probably sick of it but rerun qplot again, this time with 4 arguments. The first 3 are the same as the last qplot command you just ran (price, data set equal to diamonds, and binwidth set equal to 18497/30). (Use the up arrow to save yourself some typing.) The fourth argument is fill set equal to cut. The shape of the histogram will be familiar, but it will be more colorful.
qplot(price, data = diamonds, binwidth = 18497/30, fill = cut)
Error in readRDS(nsInfoFilePath) : error reading from connection
I cannot solve this problem even after a long search on the internet
I encountered the same error while using ggplot2, even with very simple data and graph.
I traced the readRDS function with the following code :
trace(readRDS, quote(print(ls.str())))
which after running the ggplot code returned something like :
Tracing readRDS(metapath) on entry
file : chr "/home/username/R/x86_64-pc-linux-gnu-library/4.1/farver/Meta/package.rds"
refhook : NULL
I reinstalled the farver package, the error disappeared and I was finally able to plot the graph I wanted.
This package (and the package.rds file) was probably not installed correctly.
I found a similar issue and the tracing command here.
I doing an exerise on RStudio [https://www.slideshare.net/thoi_gian/iris-data-analysis-with-r][1]
tried below command im getting Error: unexpected symbol in "Scatter plot"
Scatter plot plot(iris, col=iris$Species) legend(7,4.3,unique(iris$Species),col=1:length(iris$Species),p ch=1) Lattice library Ggplot2 library
You have copied too much text from the slideshare slide, and as a result you are getting the error because that is not proper syntax. The following should work:
data(iris)
plot(iris, col=iris$Species)
Hi im a real self teaching R newbie:
I'm following a GWR tutorial here
but already on first page my code fails at
colours = c(“dark blue”, “blue”, “red”, “dark red”)
Creates a colour palette and at spplot
spplot(map, “Nocars”, cuts=quantile(Nocars), col.regions=colours)
Error: unexpected input in "colours = c(�"
and the same for spplot
Error: unexpected input in "spplot(Nocars, �"
Could you please help, im sure its something silly.
I am trying to generate a plot using heatmap.2 and print to a pdf_document using Rmarkdown.
Whether I call heatmap.2 from the console or in an .Rmd, the plot appears perfectly exactly as I want it. But additionally, I receive the error message:
## Error in plot.new(): figure margins too large
I can force knitr to continue processing using error=TRUE, but the error message is still printed. I also have set
echo=FALSE, warning=FALSE, message=FALSE
which I thought would suppress the message, but it doesn't. I have tried using invisible() as per this question, but it seems to do nothing.
I have also tried "fixing" the error by adjusting my plot parameters in heatmap.2 with no success-- it seems to complain when one of my columns in lhei is too skinny. Since the plot looks fine, I am not worried about it unless there is no other way to suppress this error message.
How can I suppress this error message in my Rmarkdown pdf?
A pretty robust way of suppressing error messages is to wrap an expression in try(...,silent=TRUE). As a general example, if we use the following code to set up a plot layout
plotIDs <- matrix(c(1:16), 4, 4, byrow = T)
layout(plotIDs, widths = c(0.5,1,1,1,1), heights = c(0.5,1,1,1,1))
calling frame() afterwards will produce an error:
R> frame()
Error in frame() : figure margins too large
Wrapping this with try, i.e.
R> try(frame(),silent=TRUE)
R>
will not produce an error message in the console.
