Sort a column in a dataframe
Dear Users
This is my dataset called mydata4. I want to sort the dataframe on the first
column PxMid which is basically a column with dates.
I've tried mydata4<-mydata4[order(mydata4$PxMid),] but it doesnt work. Could
it be because these are dates?
Please help I'm really stuck !!
Thank you for your time.
Regards
Meenu

ggplot2 : commands on one line vs two lines.
I have just started using ggplot2 and I seem to be doing something stupid
in writing ggplot2 commands on more than one line.
In the example below the commands on one line are working fine, but as
soon as I put them on two lines I get an error. Can any one point out
what I am doing wrong? It must be something blindingly simple.
Thanks
