plotmath

I need to add a line break but I am struggling with the atop function in expression() . The main is the part I would like to break into two lines. > plot (DAC~Chlo,data=brazilw, pch=15,col="red",cex=0.5, main=expression("Fig. 3. Relationship between diffuse attenuation coefficient at 490 nm (K"[d]*") and chlorophyll concentration at three coral reef sites"), xlab=expression("Chlorophyll concentration (mg "*m^{-3}*")"), cex.lab=0.8, cex.main=0.8, cex.axis=0.8, font.main=1, ylim=c(0,0.3), xlim=c(0,3.5), ylab=expression("K"[d]*"(m"*-1^{-1}*")")) You did not specify, where you want to break the

Following works, (copy & paste into R) a=123 plot(1,1) legend('bottomleft',legend=bquote(theta == .(a))) I want to have multiple items in the legend. All with greek letters. As a simple example, if I repeat the item twice the code does not work anymore a=123 plot(1,1) legend('bottomleft',legend=c(bquote(theta == .(a)),bquote(theta == .(a)))) I have tried many more complicated expressions but they all did not work. Any help will be appreciated. In this case, plotmath is not able to coerce the list of calls to expressions. > cs <- c(bquote(theta == .(a)),bquote(theta == .(a))) > cs [[1]] theta =

I have a dataframe with several variables that I wish to label and then use in several ggplots. I have applied labels using the labeller package with the following code. library(tidyverse) library(labeller) library(ggpubr) example.df <- data.frame( origin = sample(c("hum_1", "mou_1"), 100, replace = TRUE), v1 = rnorm(100, 100, 5), v2 = rnorm(100, 10,5), v3 = rnorm (100, 25, 5)) example.df <- example.df %>% set_variable_labels(origin = "original sample", v1 = "effect of Rx", v2 = "response", v3 = "weight (kg)") This gets the labels to show up in the dataframe. However, when I use ggqqplot from

Is it possible to pass partially italicized text labels into ggplot? I have tried using the expression and italic commands ( expression(paste(italic("some text"))) ), but these cannot be passed into a data frame because the result of the commands is not atomic. Setting the parameter fontface = "italic" also doesn't suffice, since this italicizes the entire label, rather than just a select set of characters in the label. For instance, I would like some necessarily italicized Latin phrases to be italicized in a label (such as "in vivo" in "in vivo point"). library(ggplot) library(ggrepel) df <-

I would like to use Greek characters, Latin characters and the percent sign in the facet labels of a ggplot2 bar chart. Greek characters can be done with 'facet_grid(.~variable, labeller=label_parsed)': a<-c("Delta~V","VarcoV","Delta~V","VarcoV") b<-c(1,2,3,4) d<-c("one","one","two","two") mydata<-data.frame(cbind(b,a,d)) ggplot(mydata,aes(x=d,y=b))+facet_grid(.~a, labeller=label_parsed)+geom_bar(stat="identity") Now I also want to add a facet label that includes % and a Latin character: a<-c("Delta~V","VarcoV","%V","Delta~V","VarcoV","%V") b<-c(1,2,3,4,5,6) d<-c("one","one","one","two","two",

In R, I use expression(theta[l]) so that the label of my plot axis is that same as $\theta_l$ from LaTeX. For esthetic reasons, I'd rather like to display $\theta_\ell$ . Can you help me? EDIT Before, I did plot(1:10, 1:10, xlab=expression(theta[l])) and I exported the resulting picture in pdf. Then, using \begin{figure}[htbp] \centerline{\includegraphics[scale=.6]{test.pdf}} \end{figure} my picture was inserted in LaTeX. Following the comments, here is what I now do: require(tikzDevice) tikz("test.tex", standAlone=TRUE, width=5, height=5) plot(1:10, 1:10, xlab="$\\theta_\\ell$") dev.off()

When I make a map using ggplot2 and attempt to italicize part of the figure title using a combination of expression() and italic() using a string, my map comes out as desired: plottitle <- expression(paste('Example map with ', italic('italics'))) crimes <- data.frame(state = tolower(rownames(USArrests)), USArrests) states_map <- map_data("state") map <- ggplot(crimes, aes(map_id = state)) + geom_map(aes(fill = Murder), map = states_map) + expand_limits(x = states_map$long, y = states_map$lat) + labs(title = plottitle) map However, when I try to do the same thing, but use an object instead of a

I am trying to make a y-axis title with both a special character and a superscript. I am able to do this, but I want the closing parentheses not to be superscripted. And that's what I'm having a problem with. I think its just a placing of my parenthesis, but I've tried (seemingly) everything. plot(WatexCl, ConcuM, col = as.numeric(1), pch = as.numeric(Depth), xlab = expression(paste("Concentration Cl ( ", mu, "moles/g dry wt)")), ylab = expression(paste("Average Conc of S- on plates ( ", mu, "Moles/cm"^"2"),)), data = plates) The one thing that often users fail to grasp is that you invariably
