Adding text outside plot doesn't work in r

Question

I have a simple dataset: 11 observations, 1 variable.

I want to plot them adding my own axis names, but when I want to change the position of them, R keeps plotting them in the exact same spot.

Here is my script:

plot(data[,5], xlab = "", xaxt='n')
axis(1, at = 1:11, labels = F)
text(1:11, par("usr")[3] - 0.1, srt = 90, adj = 1, labels = names, xpd = TRUE)

I am changing the -0.1, to any number but R keeps placing the labels in the exact same spot. I tried with short names like "a" but the result is the same.

Thanks in advance

My data:

10308.9
10201.6
12685.3
3957.93
7677.1
9671.7
11849.4
10755.7
11283.4
11583.8
12066.9

names <- rep("name",11)

Is there a way to change the positions of the labels using axis? I explored the ?axis page but couldn't find it. If the problem can be solved using labels that would great! — GabrielMontenegro

I am trying with mtext and axis but I can't do it. Could you show me which parameters to use so I can have the mtext the same way I wanted it using text? — GabrielMontenegro

My ggplot solution:

# creating the sample dataframe
data <- read.table(text="10308.9
10201.6
12685.3
3957.93
7677.1
9671.7
11849.4
10755.7
11283.4
11583.8
12066.9", header=FALSE)

# adding a names column
data$names <- as.factor(paste0("name",sprintf("%02.0f", seq(1,11,1))))

#creating the plot
require(ggplot2)
ggplot(data, aes(x=names, y=V1)) + 
  geom_bar(fill = "white", color = "black")

which gives: enter image description here

When you want to change the order of the bars, you can do that with transform:

# transforming the data (I placed "name04" as the first one)
data2 <- transform(data,
                   newnames=factor(names,
                                   levels=c("name04","name01","name02","name03","name04","name05","name06","name07","name08","name09","name10","name11"),
                                   ordered =TRUE))

#creating the plot
ggplot(data2, aes(x=newnames, y=V1)) + 
  geom_bar(stat="identity", fill="white", color="black")

which gives: enter image description here
