Add padding around image in PDF document

Question

I have a series of images back-to-back and I would like them to be further separated when I knit a PDF file than whatever the default is.

For example, in the following document:

 ---
title: "Image Test"
output: pdf_document
---


```{r echo = FALSE, fig.height=3}
vec1 <- rnorm(100)
vec2 <- rnorm(100)

plot(vec1)

plot(vec2)
```

I would like to control the distance between the plots. The only thing I've found so far is to keep intermediate TeX and put in newlines manually.

您可以将两个图放在单独的块中，然后将LaTeX \\ newline放在两者之间
