plot many dfs in ggplot

Hi all,

I have another question. There are several dataframes, each has the same
columns: time, varA, varB, varC, etc. If I want to plot time ~ varA of each
dataframe, where different dataframe names use different colors. How to do
this in ggplot? Thanks for your help.

Right now, I tried to use the code below, but very laborious, and needs
colors manually.

fig1 = ggplot()+
    geom_path(data=df1, aes(x=time, y= varA, color= 'df1'))+
    geom_path(data=df2, aes(x=time, y= varA, color= 'df2'))+
    geom_path(data=df3, aes(x=time, y= varA, color= 'df3'))+
    ...
    scale_color_manual('', limits=c('df1', 'df2', 'df3', ...),
values=c('blue', red', 'green', ...))
show(fig1)

Hi.

Hm. I would add a column indicating data frame and merge/rbind all data
frames.

Something like

df1$fr <- 1
df2$fr <- 2

dfkompl <- rbind(df1, df2)

ggplot(dfkompl, aes(x=time, y=varA, colour=factor(fr))

Cheers
Petr

Thanks, but rbind/merge function only combines two dataframes each time,
how to work on multiple dataframes? Thanks again.

Not quite - this works: rbind(df1, df2, df3, df1, df2, df3)

Or if the have your data.frames in a list, use do.call:

df.lst <- list(df1, df2, df3, df1, df2, df3)
do.call(rbind, df.lst)

You might take a look at the facet functionality in ggplot once you are
ready to build your plots.

Thanks. How to add an additional column, with the name of each dataframe's
name?
