如何在R中的单线图上绘制矩阵的列

I created a function which reads data from a txt file to create a table, some data manipulation occurs and then the results are put into a matrix. This is a sample of the result:

我创建了一个函数，它从一个txt文件中读取数据来创建一个表，一些数据操作发生，然后结果被放入一个矩阵中。这是结果的一个例子:

          Canada     France       Germany      Italy        Japan        
1973 0.107843137 0.13583815  0.0684713376 0.19417476  0.231732777
1974 0.108407080 0.11704835  0.0596125186 0.17073171  0.116949153
1975 0.075848303 0.09567198  0.0436005626 0.16666667  0.095599393
1976 0.077922078 0.09563410  0.0363881402 0.19345238  0.081717452
1977 0.089500861 0.09108159  0.0273081925 0.12468828  0.042253521

I'm trying to figure out how I can plot this data on a graph. I want to have the years as the x - axis and the inflation rate as the y - axis. So in the end I would like one graph with lines (in different colours) for each country.

我试着把这些数据画在图上。我想用年份作为x轴，通货膨胀率作为y轴。最后，我希望每个国家都有不同颜色的线条。

Is this possible to do?

这可能吗?

Any help appreciated, thank you.

谢谢您的帮助。

Try

试一试

matplot(rownames(m1), m1, type='l', xlab='Years', ylab='rate', col=1:5)
legend('bottomright', inset=.05, legend=colnames(m1), 
                            pch=1, horiz=TRUE, col=1:5)

or using ggplot

或者使用ggplot

library(ggplot)
library(reshape2)

ggplot(melt(m1), aes(x=Var1, y=value, col=Var2))+
                                          geom_line()

data

m1 <- structure(c(0.107843137, 0.10840708, 0.075848303, 0.077922078, 
0.089500861, 0.13583815, 0.11704835, 0.09567198, 0.0956341, 0.09108159, 
0.0684713376, 0.0596125186, 0.0436005626, 0.0363881402, 0.0273081925, 
0.19417476, 0.17073171, 0.16666667, 0.19345238, 0.12468828, 0.231732777, 
0.116949153, 0.095599393, 0.081717452, 0.042253521), .Dim = c(5L, 
5L), .Dimnames = list(c("1973", "1974", "1975", "1976", "1977"
), c("Canada", "France", "Germany", "Italy", "Japan")))

This can be done, e.g., using a for-loop, but much more efficiently using the function matplot() As an example:

这可以实现，例如，使用for循环，但是更有效地使用函数matplot()作为示例:

# d is the data frame holding your example data.
matplot(d, type="l", ylim=c(0,0.3))

# You can change the appearance of the plot with usual graphical parameters
matplot(d, type="l", ylim=c(0,0.3), lwd=4, col=1:5, lty=1)
