Undo layout in R

阅读更多关于 Undo layout in R

问题 I initially create a plot which is a combination of boxplot & histogram. For this I set nf <- layout(mat = matrix(c(1,2),2,1, byrow=TRUE), height = c(1,3)) par(mar=c(2,2,1,1)) # Draw box plot # Draw histogram After this I need to create a regular plot. But I find that all subsequent plots try to follow the same layout. One on top and another one below. How can I reset the layout to default? Should I use nf <- layout(mat = matrix(c(1,1),1,1, byrow=FALSE)) Thanks Ganesh 回答1: Yes, use: par(mfrow

问题 I have an app that lets you click buttons to add and subtract +5 or -5 and +1 or -1 from a starting value of 20.

问题 I have navigation buttons that increase in width from 100px, to 150px when hovered over : nav li:hover{ width:150px; } But using javascript I have made it so that which ever option has been selected, will continue to have a width of 150px.

The only trouble is that once I have them log in, and I create a session, that session seems to mysteriously disappear after a few minutes, and they're mysteriously bounced back to the login page (which is what happens if someone is on the training video page without being signed in.

问题 I am new to JS and JQuery - I used to program in basic in the 80's and although I have a sketchy understanding of variables and arrays, I admit I haven't got to grip with all the brackets in js. I know CSS and HTML well. Through googling I have almost got what I want, which is for a line of text to move from R to L, fade and a new line to do the same thing.
