...ied to do the sqrt(var(x)) but that did'nt work as well, Here is my data genes 15 24 63 40 25 42 46 35 23 53 37 45 30 37 50 55 40 51 30 48 x<-sd(genes[1:5,]) y<-sqrt(var(genes[1:5,])) I get 4 sds for the 4 columns instead of 5 sds for my 5 rows.

...addition: Warning messages: 1: argument is not numeric or logical: returning NA in: mean.default(x) 2: argument is not numeric or logical: returning NA in: mean.default(y) Could someone kindly give me pointers regarding the error. This worked fine with 2 other data sets. Thank You.

...ver, my results tell me vis-versa ,it actually compares every element of the vector V with 0.5 and that is waht i want it to do. Using a for loop is expensive and time consuming since my actual vector is 15000 values. Any help to rectify the warning i get is appreciated. Thank You.

...],genes[,3:4]) > stu$p.value [1] 0.4198002 i get 1 pvalue for the entire col1:col2 Vs col3:col4. I am trying to get 5 p values for the 5 rows i have. I am trying to avoid a for loop coz my actual data has 56000 rows and its taking more than 4 minutes to compute. Thanks in advance.

...all 20000 raw values as the start values. I'm getting no sd in my new curve. Can someone gimme some pointers to get started here. I need my nls to spit out sd and mean of the new fit which it does'nt. is there a better function or can i somehow get around this. Thanks in advance.

...r my project otherwise. All i need is the SD and MEAN. Can someone help me to customise. I frankly did not understand the nls code at all. I have 10 x and 10 y values from a histogram. I need to use nls to do the best fit and give me the mean and sd of this new fit. Thanks in advance Choudary Jagarlamudi Instructor Southwestern Oklahoma State University STF 254 100 campus Drive Weatherford OK 73096 Tel 580-774-7136

...problem is that I have a "n parameter" curve and I want the optimal fit. The NLS procedure gives me final function values and not the individual parameter estimates that were used to define this "best" fit. What function can I use to get these parameters? Thanks Choudary Jagarlamudi Instructor Southwestern Oklahoma State University STF 254 100 campus Drive Weatherford OK 73096 Tel 580-774-7136 [[alternative HTML version deleted]]

...nding average value. I have a copy of the 1-D vector to recreate the original 1-D vector for each loop iteration. My original vectors consist of 54,000 values and I am trying to avoid using loops as much as I can to gain speed. Any advice will be greatly appreciated. Thanks in advance.

...non linear least square curve fit. I need the mean and sd of this new fit to proceed to my next module.I'm not sure if i'm on track. Excuse me if this sounds too naive.If nls is not what i should be using can you please give me some pinters to solve this. Thanks in advance.

...xis as of the 1st(histogram) plot to plot the second. My second plot is creating its own axis and causing my plot to extend the entire histogram instead of getting a subplot on a portion of the histogram. I tried 'fig' and 'new' parameters with no luck.

...a histogram for 6000 values. I am told to plot experimental vs theoretical vlaues from the histogram and do a non linear least square curve minimization and compute the mean and sd of the new x values.Excuse me if this sounds too naive.Can you help me in getting a start on this one.
