Dear R community
I am trying to make an XY plot that shows temperature (y axis) as a
function of time (x axis) but I am having some problems. When I use the
code shown below:
1. my plot does not show any of the y-axis labels even though there is
plenty of white space there (i.e.: I am getting no y-axis title, and no
y-axis labels at each tick mark). Is my command syntax incorrect?
2. Also, I was wondering... is there a way to tell R to plot the last 30
days of data in the x-axis?
Thank you so much in advance!!
Here's my code so far:
bdata=read.table('cleandata.asc',header=FALSE)
dates1 <- strptime(paste(bdata$V2, bdata$V3), format="%m/%d/%Y %H:%M:%S")
temp1 = bdata[,4]
par(mar=c(5, 6, 4, 2))
plot(dates1, temp1,type="o",col="red",pch=20,xlab="x axis", main="my plot",
ylab="y axis", ylim=c(0,40), yaxp = c(0,40,10))
PS: just fyi, my data looks like this:
