I have a list which has multiple vectors (total 80) of various lengths. On the x-axis I want the names of these vectors. On the y-axis I want to plot the values corresponding to each vector. How can I do it in R?

*How* do you want to plot them? As boxplots? – Konrad Rudolph Mar 26 '15 at 12:43

Provide a small reproducible example of your data. Are those vectors numeric? – talat Mar 26 '15 at 12:43

Those vectors have timestamp values. These timestamps are the outliers of the data. Ex: timeinstancelist – tushaR Mar 26 '15 at 12:47

Have a look at https://stackoverflow.com/questions/5963269/ to find out how you can provide a reproducible example. – talat Mar 26 '15 at 12:50

@KonradRudolph No, I just want to plot the timestamps on the y-axis as point type plots. – tushaR Mar 26 '15 at 12:53

One way to do this is to reshape the data using reshape2::melt or some other method. Please try and make a reproducible example. I think this is the gist of what you are after:
set.seed(4)
mylist <- list(a = sample(1:50, 10, T),
b = sample(25:40, 15, T),
c = sample(51:75, 20, T))
mylist
# $a
# [1] 30 1 15 14 41 14 37 46 48 4
#
# $b
# [1] 37 29 26 40 31 32 40 34 40 37 36 40 33 32 35
#
# $c
# [1] 71 63 72 63 64 65 56 72 67 63 75 62 66 60 51 74 57 65 55 73
library(ggplot2)
library(reshape2)
df <- melt(mylist)
head(df)
# value L1
# 1 30 a
# 2 1 a
# 3 15 a
# 4 14 a
# 5 41 a
# 6 14 a
ggplot(df, aes(x = factor(L1), y = value)) + geom_point()
