x<- structure(list(count = c(4259120, 4317840, 4444000, 4254240,

plot(x$the_date, x$count, type="l", xaxt = "n", xlab = "")
axis(1, labels = FALSE)
labels<-x$the_date
labels<-format(labels, format="%b-%d-%Y")
text(x$the_date, par("usr")[3] - 0.75, srt = 55, adj = 1, labels = labels, xpd = TRUE)
I've tried adjusting the par("usr")[3] - 0.75 offset as specified here, but the labels aren't moving at all.
我已经尝试调整此处指定的par（“usr”）[3] - 0.75偏移量，但标签根本没有移动。

You can a trick like this using 2 calls to axis functions. I am using here axis.Date since you deal with dates(better for formatting). Then you can ply with line argument t play with labels positions.
你可以使用2次调用轴函数这样的技巧。我在这里使用axis.Date，因为你处理日期（更好的格式）。然后你可以使用行参数来播放标签位置。
axis(1,labels=FALSE)
axis.Date(1,at = x$the_date,las=2, format= "%m-%d",line=0.5,tick=FALSE)
