Hi, I have a data matrix in which there are 1000 rows by 30 columns. The first column of each row is a numeric indicating the number of trips taken to a particular location with location attributes in the following column entries for that row. I want to repeat each row based on the number of trips taken (as indicated by the number in the first column)...i.e., if 1,1 indicates 4 trips, I want

Greetings, I am using the nlm function in a minimization exercise but have consistently received the code: "last global step failed to locate a point lower than 'estimate'...." So it seems that this function is only finding a local minimum, not necessarily a global minimum. Does anyone have a suggestion or recommendation for an alternative package or function within R

Hello, Sorry if this is a repeat, having trouble finding what I need on archive and am a novice with graphics in R! I have plotted the results of a logit regression by factor, where "city" is the factor set name. The problem is city names are too long and I need to rotate them 90 degrees along the xaxis. This is what I've tried... plot(city, predicted.probability, xlab =
